I have a form in which I have made File no field which hold the Integer value like 1-2-3-4 and so on.
I want that ,when I save a form which has file no 1 ,and then after when I want to save the next record it should remember the last file no and increment by 1.
I have not coded yet anything because I don't know if it is possible?

It definitely is possible. You just need to use a variable to hold the value, and use that to display in the field. Every time you save a file, increment the value and refresh the displayed field.

thanks for the Idea I'm working on it.
EDIT:
I managed to do what I wanted BUT...
It only happens till the application is open and I'm saving data one after one...as soon as I close to application and opens in again I have see the last file no and enter the next file no manually.
with this code
String filenostr = filenotxtfield.getText();
statement.setString(1,filenostr);
int fileno=Integer.parseInt(filenostr);
fileno++;
String convertno=String.valueOf(fileno);
filenotxtfield.setText(convertno);
statement.executeUpdate();
int rowsAffected = statement.executeUpdate();
if(rowsAffected > 0)
{
JOptionPane.showMessageDialog(null, "Data Inserted successfully!");
}
else
{
JOptionPane.showMessageDialog(null, "Data is not Inserted!", "Not successfully", JOptionPane.ERROR_MESSAGE);
}
statement.close();
con.close();
Addition to that I'm getting error on line
int rowsAffected = statement.executeUpdate();
ERROR:
com.microsoft.sqlserver.jdbc.SQLServerException: Violation of PRIMARY KEY constraint 'PK__Employer__6F09E6800F975522'. Cannot insert duplicate key in object 'dbo.Employer'.

I'm able to display the value after data is saved, but it is showing me wrong value with this code.
int fileno1=Integer.parseInt(Result.getString(2));
int increment = ++fileno1;
String convertno1=String.valueOf(increment);
filenotxtfield.setText(convertno1);
If 1 and 2 file no already exists after entering 3rd number manually and then save it ,it is showing me 2 not 4.?

That code looks fine as it stands, but you are not saving the updated count anywhere.

Do I have to save it in the database and then retrieve it?
int increment = ++fileno1;
I have to save increment in the database?
|

It depends on how long you need the value, but you have to save it somewhere. If you only need the value for a single execution of the program, then just keep it in memory. If you want to continue where you left off with another separate execution, then you need to kepp it somewhere permanent, database, property etc.

ok right now I have not made is permanent,but I think I will save it in the database so when the application loads it will still remember the last file no ...thanks for the Idea.
Right now I have done it with this code.
int fileno1=Integer.parseInt(Result.getString(2));
int increment = ++fileno1;
int increment2 = ++increment;
filenotxtfield.setText(Integer.toString(increment2));
I have used this code after inserting the data in the database.So now as you suggested I'm working on how to show the next file no upon application starts.

I'm not sure if you're aware of this. But what this code does is essentially:
int fileno1=Integer.parseInt(Result.getString(2));
fileno1 = fileno1 + 1;
int increment = fileno1;
increment = increment + 1;
int increment2 = increment;
filenotxtfield.setText(Integer.toString(increment2));
if you just want to increment the value of fileno1 (and don't need those variables increment and increment2) by 2:
int fileno1=Integer.parseInt(Result.getString(2));
fileno1 = fileno1 + 2;
filenotxtfield.setText(Integer.toString(fileno1));

Hey,
This will be difficult to explain. I'm not sure if you'll understand. Don't know how to describe it in a good way.
We are 2 developers.
I wrote 2 different WCF's in C# and there are several that will follow. They all share 7 common functions that a user is able to call.
My mate wrote a programm that takes those WCF's.
You can "login" to his program and Choose one of my WCF's via name. And then his program will forward all messages from the chosen WCF to you.
We tried the following:
Create a WebService in Java with those 7 functions and download the WSDL.
Then change the endpoint-URL inside the generated files to the WCF-URL that the user has chosen.
The problem is microsoft.
Microsofts WCF has a unusual WSDL-File.
The same for the .asmx-Webservices.
They are different from the Java - WSDL (Therefore the generated sources are different, too) though the provided functions are the same.
From Java you can consume both asmx and WCF - Services,
but not in a generic way, because when we do it as we do, we get the message that the WSDL at this endpoint is different from the WSDL that we have.
I hope the text was not toooooo confusing.
Does anyone know a solution ?
Greetings,
SheraX

This may be a silly question for Java experts, but even for some one who has some years of Java experience like me, it is still an easily ignored topic. And even the senior developers on our team seem to make mistakes with these.
I want to understand the operators on the Java Integer class. What is Java doing when comparing two Integers? For example, let's say we have Integer a and Integer b. Does Java do reference comparison or value comparison on ==, !=, <, >, <=, >= operators?
And if one of the operator is an Integer and the other is a constant, what does Java do with ==, !=, <, <>, <=, >=?
And if one of the operator is an Integer and the other is an int, what does Java do?
In my experience, seems that Java does reference comparison with two Integers, and seems that it does value comparison with one Integer and one constant.

The following test program shows what happens:
public class Test {
public static void main(String[] args) {
Integer a;
Integer b;
a = 10;
b = 10;
if (a == b)
System.out.println("True");
}
}
You can also verify by disassembling the class via javap -c.
