When I compile this, I get an error:
import java.lang.*;
import java.util.Scanner;
public class Test
{
public static void main(String[] args)
{
Scanner console = new Scanner(System.in);
}
}
The error is "Cannot resolve symbol class Scanner".
Anyone know what's wrong here?
Everything makes sense in someone's mind

don't know how you're compiling your code, but I have absolutely no error with the following code :
package test;
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
}
}

Hi,
First time programming JSP as I have to do it for an uni assignment. Basically I have created a register HTML and JSP page:
<br />
<!-- Register.html --><br />
<html><br />
<head><br />
<title>Register Form</title><br />
</head><br />
<br />
<body><br />
<h1>Hotel Account</h1><br />
<form><br />
<br />
<br />
ACTION="Register" METHOD="POST"><br />
<br />
<pre><br />
Customer Name: <input type="text" name="CustomerName"><br />
Customer No: <input type="text" name="CustomerNo"><br />
Customer Type: <input type="text" name="CustomerType"><br />
Customer Comp: <input type="text" name="CustomerComp"><br />
Customer Address: <input type="text" name="CustomerAddress"><br />
Nationality: <input type="text" name="Nationality"><br />
Passport No: <input type="text" name="PassportNo"><br />
Travel Agency: <input type="text" name="TravelAgency"><br />
Password: <input type="text" name="Password"><br />
</input></input></input></input></input></input></input></input></input></pre><br />
<br />
<input type="SUBMIT" value="Submit"><br />
</input></form><br />
</body><br />
</html><br />
From there what I am trying to do is insert all the data gathered from the inputs into an DB.
Now I have decided to do 4 Java classes and 1 servlet inorder to achieve this.
I have created the account class to use the getter and setter methods:
<br />
<br />
<br />
<br />
public abstract class Account<br />
{<br />
String CustomerName, CustomerType, CustomerComp, CustomerAddress, Nationality, PassportNo, TravelAgency, Password;<br />
int CustomerNo;<br />
<br />
<br />
<br />
public Account()<br />
{<br />
CustomerName = "";<br />
CustomerNo = 0;<br />
CustomerType = "";<br />
CustomerComp = "";<br />
CustomerAddress = "";<br />
Nationality = "";<br />
PassportNo = "";<br />
TravelAgency = "";<br />
Password = "";<br />
<br />
}<br />
<br />
<br />
public Account(String cName, int cNo, String cType, String cComp, String cAdd, String n, String pNo, String tAgency, String pass)<br />
<br />
{<br />
CustomerName = cName;<br />
CustomerNo = cNo;<br />
CustomerType = cType;<br />
CustomerComp = cComp;<br />
CustomerAddress = cAdd;<br />
Nationality = n;<br />
PassportNo = pNo;<br />
TravelAgency = tAgency;<br />
Password = pass;<br />
}<br />
<br />
public void setCustomerName(String cName)<br />
{<br />
CustomerName = cName;<br />
}<br />
<br />
public void setCustomerNo(int cNo)<br />
{<br />
CustomerNo = cNo;<br />
}<br />
<br />
public void setCustomerType(String cType)<br />
{<br />
CustomerType = cType;<br />
}<br />
<br />
public void setCustomerComp(String cComp)<br />
{<br />
CustomerComp = cComp;<br />
}<br />
<br />
public void setCustomerAddress(String cAdd)<br />
{<br />
CustomerAddress = cAdd;<br />
}<br />
<br />
public void setNationality(String n)<br />
{<br />
Nationality = n;<br />
}<br />
<br />
public void setPassportNo(String pNo)<br />
{<br />
PassportNo = pNo;<br />
}<br />
<br />
public void setTravelAgency(String tAgency)<br />
{<br />
TravelAgency = tAgency;<br />
}<br />
<br />
public void setPassword(String pass)<br />
{<br />
Password = pass;<br />
}<br />
<br />
public void setAllAccountData(String cName, int cNo, String cType, String cComp, String cAdd, String n, String pNo, String tAgency, String pass)<br />
{<br />
CustomerName = cName;<br />
CustomerNo = cNo;<br />
CustomerType = cType;<br />
CustomerComp = cComp;<br />
CustomerAddress = cAdd;<br />
Nationality = n;<br />
PassportNo = pNo;<br />
TravelAgency = tAgency;<br />
Password = pass;<br />
}<br />
<br />
public String getCustomerName()<br />
{<br />
return CustomerName;<br />
}<br />
<br />
public int getCustomerNo()<br />
{<br />
return CustomerNo;<br />
}<br />
<br />
public String getCustomerType()<br />
{<br />
return CustomerType;<br />
}<br />
<br />
public String getCustomerComp()<br />
{<br />
return CustomerComp;<br />
}<br />
<br />
public String getCustomerAddress()<br />
{<br />
return CustomerAddress;<br />
}<br />
<br />
public String getNationality()<br />
{<br />
return Nationality;<br />
}<br />
<br />
public String getPassportNo()<br />
{<br />
return PassportNo;<br />
}<br />
<br />
public String getTravelAgency()<br />
{<br />
return TravelAgency;<br />
}<br />
<br />
public String getPassword()<br />
{<br />
return Password;<br />
}<br />
<br />
<br />
public String getAllAccountData()<br />
{<br />
return "CustomerName = " + CustomerName +<br />
"; CustomerNo = " + CustomerNo +<br />
"; CustomerType = " + CustomerType +<br />
"; CustomerComp = " + CustomerComp +<br />
"; CustomerAddress = " + CustomerAddress +<br />
"; Nationality = " + Nationality +<br />
"; PassportNo = " + PassportNo +<br />
"; TravelAgency = " + TravelAgency +<br />
"; Password = " + Password;<br />
}<br />
Then I made an Account DB class to hold customer info:
<br />
<br />
<br />
<br />
import java.sql.*;<br />
<br />
<br />
<br />
<br />
public class AccountDB<br />
{<br />
<br />
static Connection connection;<br />
static final String dbDriver =<br />
"sun.jdbc.odbc.JdbcOdbcDriver";<br />
static final String dbUrl = "jdbc:odbc:HotelDatabase1";<br />
static final String dbName = "HotelDatabase1";<br />
static final String dbUser = " ";<br />
static final String dbPassword = " ";<br />
<br />
<br />
public Connection getConnection()<br />
{<br />
System.out.println("Getting Database driver" );<br />
try<br />
{<br />
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver" );<br />
<br />
}<br />
catch( ClassNotFoundException e )<br />
{<br />
System.err.println(<br />
"Cannot load database driver: for DB2, "<br />
+ "your classpath must include "<br />
+ "SQLLIB\\JAVA12\\DB2JAVA.ZIP." );<br />
}<br />
<br />
<br />
<br />
if ( connection != null )<br />
return connection;<br />
try {<br />
connection = DriverManager.getConnection(<br />
dbUrl, dbUser, dbPassword);<br />
} catch( SQLException e ) {<br />
System.err.println(<br />
"Cannot connect to database: "<br />
+ "check that Access is running and "<br />
+ "the Hotel Database database exists." );<br />
}<br />
return connection;<br />
}<br />
public ResultSet getAllCustomerInfo() {<br />
ResultSet rs = null;<br />
try {<br />
Statement statement =<br />
getConnection().createStatement();<br />
String sql =<br />
"SELECT * FROM Customer";<br />
System.out.println( sql );<br />
statement.executeQuery( sql );<br />
rs = statement.getResultSet();<br />
} catch( SQLException e ) {<br />
System.out.println(<br />
"SQLException " + e.getMessage() );<br />
} finally {<br />
return rs;<br />
}<br />
}<br />
public void addCust( CustomerAccount account )<br />
throws SQLException, DBopException<br />
{<br />
int nrows = 0;<br />
Statement statement = getConnection().createStatement();<br />
String sqlString ="INSERT INTO Customer VALUES ("<br />
+ account.getCustomerName()<br />
+ ",'"<br />
+ account.getCustomerNo()<br />
+ "','"<br />

+ ")";<br />
<br />
<br />
nrows = statement.executeUpdate( sqlString );<br />
if ( nrows != 1 )<br />
{<br />
throw new DBopException(<br />
"Instead of 1 row, "<br />
+ nrows<br />
+ " were inserted." );<br />
}<br />
return;<br />
}<br />
public void updateCust( CustomerAccount account )<br />
throws SQLException, DBopException<br />
{<br />
int nrows = 0;<br />
Statement statement =<br />
getConnection().createStatement();<br />
String sql =<br />
"UPDATE Customer SET "<br />
+ "CustomerName = "<br />

+ " WHERE CustomerNo="+account.getCustomerNo();<br />
<br />
<br />
System.out.println( sql );<br />
nrows = statement.executeUpdate( sql );<br />
if ( nrows != 1 )<br />
{<br />
throw new DBopException(<br />
"Instead of 1 row, "<br />
+ nrows<br />
+ " were updated." );<br />
}<br />
return;<br />
}<br />
}<br />
<br />
A customer account java class for the customer account itself:
<br />
<br />
<br />
<br />
public class CustomerAccount extends Account<br />
{<br />
public CustomerAccount(String cName, int cNo, String cType, String cComp, String cAdd, String n, String pNo, String tAgency, String pass)<br />
{<br />
super(cName, cNo, cType, cComp, cAdd, n, pNo, tAgency, pass);<br />
<br />
}<br />
<br />
<br />
}<br />
<br />
<br />
A DBopexception java class for the exception:<br />
<br />
<br />
<br />
<br />
<br />
public class DBopException extends Exception {<br />
<br />
public DBopException() {<br />
this("Could not complete AccountDB database operation");<br />
}<br />
<br />
public DBopException(String s) {<br />
super(s);<br />
}<br />
}<br />
And finally a register servlet:
<br />
<br />
import java.io.*;<br />
import java.text.*;<br />
import java.sql.*;<br />
import javax.servlet.*;<br />
import javax.servlet.http.*;<br />

<br />
<br />
<br />
public class Register extends HttpServlet<br />

private CustomerAccount customerAccount;<br />
private String query;<br />
<br />
public void init( ServletConfig config ) throws ServletException<br />
{<br />
<br />
accountDB = new AccountDB();<br />
accountDB.getConnection();<br />
}
<br />
protected void doPost( HttpServletRequest request,<br />
HttpServletResponse response )<br />
throws ServletException, IOException<br />
{<br />
response.setContentType( "text/html" );<br />
PrintWriter out = response.getWriter();<br />

<br />
out.println( "" );<br />
<br />

// handle database exceptions by returning error to client<br />
catch( SQLException sqlException ) {<br />
sqlException.printStackTrace();<br />
}<br />
}<br />
<br />
} // end class RegisterServlet<br />
Now the problem is when the project runs and I have inserted all the data once I submit it says SQLException..I have tried other ways but cant find a solution for it..could it be that I have too many classes? IS there a better way to achieve what I want?
Any help would be appreciated.
PS. Ignore the comments in the code as they indicate the wrong things.

hi, every one....
I done project on core java..for load balancing in a distributed system............
our main goal of the project is to "avoid the network crash".......balancing a load..........
problem statement:"whenever an end point systems are heavily loaded..network may crash..and it wil cause..irreversible damage to the network"
soln..we find out are:..find out the which client..is heavily loaded and which client is having fewer load...the..client..which is havily loaded...that client..process is transfarring..to the client..which is..having..lower load"..........
but..right now i'm facing ..problem is that:...how to transferring a process from one client to another client..if the process trasferred from one process name called:"internetexplorer"...same..process should transffer to the another client...and process should..in same..status...that is:..if any thing downloading from internet..that time..client becomes,..heavily..loded..then the same process can be transffered to the client which is having lower load..again...proces..of "inetrnetexplorer"...remains..same..of..coninuing..downloading..processs"...................please...if any one....know about..the java code..for..this..please...help me!!!!

hello all,
i am new to java and
I'm trying to add a new library 'hibernate-3.2.4.sp1.tar.zip', to netbeans. I understand that to do so, I click tools;libraries;add new library and then select the folder which contains all the .java files. I've done this, but still when I try to import that library, it the IDE says that it doesn't exist? What's the issue? Either the correct procedure for how to add new libraries or an analysis of my issue from my vague description would be great! Also, when I name the library, do I import the name I give it, or the name of the file? For example, if the name of the file is hibernate, and it contains some files. i write
import org.hibernate.*;
but in org package doesn't exist the hibernate.
Regards!

Hi,
I have a Fortran program which I have to convert into Java originally. I have converted the code completely but can't get appropriate resutls. The code contains lot of arithmetic calculations using double precision data type of Fortran.
I believe the data types of Java are based differnt than Fortran. Fortran's double precision type is based on IEEE756. I want to know how to convert these double precision calculations into Java. For example:
double precision d1 = 0.3648564D0;
d1**2
DSIN(d1)
DCOS(d1)
The above are my main concerns which I find very difficult to convert. I use Math.sin & cos for DSIN & DCOS. But Fortran 77 deals somthing differntly with double precision. How to convert/translate that into our java application is what I am looking for.
If you can provide the same for C++ that would also be a plus for me, I will use the code accordingly of Java application.
Please help me out. Am stuck up very badly.
Thanks
Terry

do you know something called "javadoc" ?  just kidding
in java (and in C++), the type double handles such precision.
then, you just have to call the correct functions, which you'll find reference in the online documentation.
in C++, just #include <cmath> and use sin() and cos() like this.
in Java, just call Math.sin() and Math.cos()...

I just finished writing this program, what it does is takes your name and assigns each letter a number and adds them up,
ie. Tanner would give you 27
The program then checks to see if the number is one or two digits, which in this case it is two (2 and 7)
It then adds those two digits together. Comments explain everything
What I would like input on is if anyone could give me a couple pointers on how to optimize my code, make it faster or take away some of the writing to reduce it's length

Oh dear.. cases totally slipped my mind. Also, I never knew that you could do something like
currentLetter = input[i]. I'm assuming that that will access the String as a character array and return the letter at position i?

TannerB wrote: I'm assuming that that will access the String as a character array and return the letter at position i?
yup. the [] operator gets the character at position passed in parameter (0-based).
also, a thing I shown in my sample, which i'm not sure you noticed, is using the characters literals instead of their ascii code... this is very handy when you come later and read back your code

Hello everybody,
I would implement it like this to avoid if or switch statements :
int incrementAmount;
for(int i = 0;i < inputLength;i++){
currentLetter = input.charAt(i);
incrementAmount = (Character.toUpperCase(currentLetter)-'A')%9+1;
firstNameTotal += incrementAmount;
}
Also we can replace :
incrementAmount = (Character.toUpperCase(currentLetter)-'A')%9+1;
By :
incrementAmount = (Character.toUpperCase(currentLetter)-'A')%('J'-'A')+1;
just to be more readable, that means "restart counting after the letter 'J'", which is better than "restart counting after the 9th letter".
I also just noticed that you don't manage the case where thirdNameTotal is equal to 0.
|
|
|
|
|
yup, that's a pretty smart implementation... i didn't took too much time to think on a better optimization, but yours is good

i have make an appliction on j2me and use digestmesage from java .securtiy but on cldc 1.1 the java.securty not supported
ihad import that

I would like to know how to debug MSJVM in Eclipse. I can see Java console of MSJVM but I can't debug my code. Please let me know if you can do it. Thanks!

you can't if you don't have the source code...
otherwise, set a breakpoint, and start your program with 'debug as...' > 'Java Application'

Sure. I have a source code. I can debug with JRE. But I can't debug with MSJVM.

My application is an applet. So, I have to add parameter into JRE. When I run the debug, I see message below:
Failed to connect to remote VM. Connection refused.
Connection refused: connect
Please advise me in this case. Thanks!

Hi everyone,
i'm working on a project and i need to draw a graph (not a chart, a network).
I think there are some classes or library to do that but i didn't find anything.
Can someone help me? Articles, links...all welcome.
Thanks in advance,
