how to find 2nd largest array if array values like{10,20,92,81,92,34}
|
|
|
|
|
|
First looking for the largest number, after that you can put:
if (larger == array[i]) continue;
else
looping it all and using the same algorithm, of course.

Hi all,
Java newbie here..
Is it possible to override/set the value of a member variable at runtime?
So for example, in the snippet below, how do I set fieldValue with the value of the data that is stored in fieldName?
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface MyField{
String fieldName() default "";
String fieldValue() default "";
}
@MyField(fieldName = "pageTitle")
public class Foobar {
private String pageTitle;
public String getPageTitle() {
return pageTitle;
}
public void getPageTitle(String pageTitle) {
this.pageTitle = pageTitle;
}
}

I think this answers your question, http://docs.oracle.com/javase/1.5.0/docs/guide/language/annotations.html[^]
Quote:
Once an annotation type is defined, you can use it to annotate declarations. An annotation is a special kind of modifier, and can be used anywhere that other modifiers (such as public, static, or final) can be used. By convention, annotations precede other modifiers. Annotations consist of an at-sign (@) followed by an annotation type and a parenthesized list of element-value pairs. The values must be compile-time constants.
Personally never used annotations for anything other than generating Java Docs and I'm not sure what your trying to use it for here? Are you really trying to define an interface?

Thanks, I'll take a look at the link. Per your question, I'm using annotations to for custom validation.
|

Annotations can be processed to produce code in various ways. The code of course would exist at run time.
If you are using an existing annotation processing system then what ever it does is what you can do, and you would look at the docs for that.
If your writing your own then add the functionality to keep track of it.

No one is going to download your code and try to debug it for you. Please edit your question and add a proper explanation of your problem.

I have this code which saves the value into database from JSpinner
SpinnerListModel monthModel = new SpinnerListModel();
String[] monthStrings = {"1Month","3Month","6Month","1Year"};
monthModel = new SpinnerListModel(monthStrings);
JSpinner spinner = new JSpinner(monthModel);
statement.setString(28,(String)monthModel.getValue().toString().toUpperCase());
But how to get that value back for Editing?
I tried
spinner.setText((String)monthModel.getValue(),29);
But it says
The method setText(String, int) is undefined for the type JSpinner
How do I get the values from Database?again to JSpinner.

You should have a database layer. It should NOT have any gui code in it.
It provides a public API that allows an external caller to interact with the layer.
The layer interacts with the database.
That public API would have a method/class that would represent "save interval" and "get interval" where the 'interval' values represent '1 month', '3 Months', '6 months' (and note that I am NOT saying to store "1 month" as a value.)
The 'save' method uses a database insert or perhaps update statement. And the 'get' uses a database query statement.
You code that and test it.
After you do that THEN your gui code, specifically the JSpinner uses the two methods.

Can anyone guide me how to write code to generate public and private keys using RSA algorithm, using your own functions? In other words, not using BigInteger etc. This seems impossible and I have a deadline of 31 October, 2013.

I'm not able to move forward with the ResultSet with this code on "next Button".
Here is the code
public void nextrecord()
{
Statement stmt = null;
String query = "select * from Employer";
try {
stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery(query);
if(rs.isBeforeFirst());
{
while(rs.next())
{
firstNameTextField.setText(rs.getString(2));
lastNameTextField.setText(rs.getString(3));
addressTextField.setText(rs.getString(4));
}
}
}
catch (SQLException e )
{
e.printStackTrace();
}
}
The problem is when I click on the next button ,it takes me to the last record and skips all the records ,I wanted to go through all the records one by one ,clicking each record one by one.
There is one record present in the text fields before pressing next button.

Separate your actions...
0. Method to query the data, then store the record set.
1. Method to display a record.
Something like [untested code]
class Hatstand
extends Stuff
{
private RecordSet recordSet;
private void submitQuery()
{
Statement stmt = null;
String query = "select * from Employer";
try
{
stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
this.recordSet = stmt.executeQuery(query);
}
catch (SQLException e )
{
e.printStackTrace();
this.recordSet = null;
}
finally
{
setRecord(true);
}
}
private void setRecord(boolean forward)
{
boolean isNull = true;
if (this.RecordSet != null)
{
if (forward && !this.RecordSet.isLast())
{
this.RecordSet.next();
isNull = false;
}
else if (!forward && !this.RecordSet.isFirst())
{
this.RecordSet.previous();
isNull = false;
}
}
if (isNull)
{
firstNameTextField.setText(null);
lastNameTextField.setText(null);
addressTextField.setText(null); }
}
else
{
firstNameTextField.setText(rs.getString(2));
lastNameTextField.setText(rs.getString(3));
addressTextField.setText(rs.getString(4)); }
}
}
}
