I didn't think such thing as a java enthusiast existed.

ikr.

Do not extend GUI Swing JComponents or any java.awt.Component for that matter and more than a few (<4) Data Members. If you do need to include more than a small number of variables (e.g more than JButton.pressed=true/false and so forth) then create a Data Member Reference to an Object instead ('Global Variable Pointer' for you C types).

If you give too many Data Members then the Object will not draw correctly. Example below:

Code: [Select]


public class NarutoChessPiece extends JButton{
   protected char type;
   protected String name="Empty Square";
   protected boolean turn=false;
   protected boolean empty=true;
   protected boolean moveMe=false;
   protected boolean player1=false;
   protected int x;
   protected int y;

}

Will not draw in a correct order from a two dimensional array for a board. By creating a Class, say 'NarutoPiece' and the moving all the Data Members from the above class into the NarutoPiece class all problems disappear.

Except for User Error which can only be eliminated with bullets or education.

You should can Java and go to C#

Writing software for parking meters is a serious business.

Code: [Select]

while ( myWallet.Money > 0)
{
EatMoreMoney(moreMoney);
System.out.println("Om Nom Nom!");
}

You bastard! I can't believe you'd write that code to steal my monies. I'm just glad you haven't figured out how to charge my cc yet...

[Apostrophe Spacemonkey]

I can only charge your credit card if you don't give me your number.

Thats not how the system works!


Code: [Select]

public class Bank extends Thief{
protected final ArrayListsuckers;
protected double phatLewts=0;
public Bank(ArrayListcustomers){
suckers=customers;
}//constructor

public void depositMoney(Customer sucker){
if(sucker.hasMoney()){
phatLewts=phatLewts+sucker.getMoney();
sucker.setMoney(0);
}//fi
}//method Take their money and laugh
}//class

I've so totally busted your elaborate ruse.

OH! I found out why this was happening.

There are methods in the Component & JComponent called:

setX(int num)
setY(int num)

IF YOU OVERRIDE THESE IN ANY WAY EVERYTHING BREAKS.


Never override these methods. Create a new method instead, like "setXX(int n)" or "setYCoordinate".


If you override the methods then the Swing's draw X & Y coordinates become a weird number.

Dont forget to change the getX() and getY() to something like "getXX()" and "getYY()".

[Pyromanik]

Then you could make a method miosis() to split your co-ordinates?

[Codex]

lol epic

[Pyromanik]

So old, but still good.
gOLDen, one might say

[Tiwaking!]

Dont forget the two required imports!
import java.lang.reflect.Method;
import java.lang.reflect.InvocationTargetException;

Code: [Select]

/**
Apparently getMethod does not allow for protected method access, but getDeclaredMethod does
*/
public void actionPerformed(ActionEvent ae){
try{
getClass().getDeclaredMethod(ae.getActionCommand()).invoke(this);
}//catch
catch(Exception e){
javax.swing.JOptionPane.showMessageDialog(null,e.toString(),ae.getActionCommand(),javax.swing.JOptionPane.INFORMATION_MESSAGE);
}//catch
}//me action performed

For some reason KeyEvents (http://docs.oracle.com/javase/1.5.0/docs/api/java/awt/event/KeyEvent.html) refuse to work properly. For example:

Code: [Select]


public void keyTyped(KeyEvent e) {
if(e.getKeyChar()==KeyEvent.VK_ESCAPE){
System.exit(0);
}//if you press escape (keyChar 27)
}//me

May or may not work. HOWEVER:

Code: [Select]


public void keyTyped(KeyEvent e) {
if(e.getKeyChar()==[b]e[/b].VK_ESCAPE){
System.exit(0);
}//if you press escape (keyChar 27)
}//me

DOES work even though KeyEvent key codes are static ints. This may be related to keyboard layout.


You have been warned

[Bell]

What happens if you use getKeyCode() instead of getKeyChar()

[oefox]

still on 1.5...oh dear

Don't upgrade to Juno, Juno is a bad upgrade over Helios/Indigo unless you turn off all validators, then it becomes quite usable.

Going to dabble in android apps over summer break, have been in spring mvc + hibernate/jpa for way too long

[Xenolightning]

Tiwa doesn't use real IDE's.

He uses the glorified notepad that is BlueJ

On the same note, just upgraded from Galileo to Helios at work because it was balls.

About Java code?

[Pyromanik]

Actually, no.
