[java] Dumbass java

Whats in the array text or numbers?

Strings.

import java.awt.*;
import java.awt.event.*;
import java.applet.*;

public class Texts21 extends Applet implements ActionListener
{

  TextArea  destination;
  Button    copy;
  String a[] = { "0","1","2","3","4","5","6","7" };

  public void init()
  {

    copy = new Button( "Copy ->" );
    copy.addActionListener( this );
    add( copy );

    destination = new TextArea( 10, 30 );
    add( destination );

    validate();
  }

  public void actionPerformed( ActionEvent e )
  {

    String temp;

    if( e.getSource() == copy )
    {
      for( int i = 0; i < a.size; ++i )
      {
         temp += a[ i ] + " ";
      }

      if( destination.getText() == "" )
      {
        destination.setText( temp );
      }
      else
      {
        destination.append( temp );
      }

    }

  }
}

it helps alot, thanks.
if i still cant get it to work i''ll post again soon, lol.

the piece of code i have works correctly, but i will have more than one array being written to the text area, i have got it to write to it, but they are all on the same line,
do you know what the return command is? so i can display each array on a seperate line.

Thanks.

JButton01.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent event) {

// Temporary String Variable, to store the arrays.
String temp;

// initalises temp to an empty string.
temp = "";
Razor [ ] razors = museum.getAllRazors();

if(razors.length == 0) {
JTextArea01.setText("Museum has no Razors");
}

for(int i=0;i
temp += razors;
// HERE IS WHERE I NEED SOMESORT OF RETURN LINE!
JTextArea01.setText("All Razors " + temp);

}

}
});


this is it if you can make head or tails of it.

Try:

TextArea01.append( new Charecter( 13 ) );

I don''t know if that will work, because for some reason I''ve never had to create a newline in a text box before. I can''t think why not.

Try sun''s website:

http://java.sun.com/j2se/1.4.2/docs/api/

Also the JAVA tutorial:

http://java.sun.com/docs/books/tutorial/index.html

JTextArea01.setText("All Razors " + temp + "\n");

To put each array entry on a separate line do something like this:

for(int i=0; i<razors.length; ++i)
{
   JTextArea01.append(razors[i] + "\n");
}

Because you eventually posted some code, I''m going to allow this thread to stay open. But be warned: Next time don''t just say "it''s not working," and ask for code, but rather post at least a link to yours since it''s very hard to help without anyone seeing it. Furthermore, you don''t want me to think it''s a homework question and close a legitimate thread

The code I posted in original reply to Arclight was just a modified version of an Applet we done in college. I didn''t even write it ''twas straight out of my network drive.

I was referring to the original poster, actually. You''re fine.
