Care to tell us what your problem is? We can only guess that it compiles, otherwise you can't run it, but what happens when you run it? Doesn't it do what you want? Does it crash? Does it throw Exceptions?

kind regards,

Jos

it does not compile...showing some error....i do not know why....can u correct this....

i have problem in those two lines that given below.......



setBounds((int)(0.5*(screenSize.width-getWidth())).(int)(0.5*(screenSize.x-getX())).(int(0.5)*(screenSize.y-getY()))



if ((choice == 1 && index==picked[0])||behind[index==-1|| newButton])

So you are having compilation problems and you weren't even able to run that code; please be as exact as possible and help us to help you: I bet the compiler didn't just whine "some error" and quit its job, it showed you the exact position where it didn't understand your code and spitted a message at you; what is that position and what did the compiler say?

kind regards,

Jos

Jos

ps. I reported your (first) reply.

Code:

---

if ((choice == 1 && index==picked[0])||behind[index==-1|| newButton])

---

What is this `behind[index==-1|| newButton]`?

That is where you first problem is....

Also this,

Code:

---

setBounds((int)(0.5*(screenSize.width-getWidth())).(int)(0.5*(screenSize.x-getX())).(int(0.5)*(screenSize.y-getY()))

---

does not make sense... its basically saying

Code:

---

int val1 = 0.5 * (screenSize.width - getWidth());
int val2 = 0.5 * (screenSize.x - getX());
int val3 = 0.5 * (screenSize.y - getY());
setBounds(val1.val2.val3);

---

'.' is not a valid operation on an int.

Break things down if you don't understand things and it usually always makes things clearer.

hey ..it is still not working.......i think i made mistake in those two lines......it's also showing some compiler error.....bt thats is not so handy bt...those two lines are handy i guess

there are lots of mistakes, I'll try to fix some of them:

Quote:

---

static ImageIcon apple = new ImageIcon ("apple.gif");
static ImageIcon bannana = new ImageIcon ("bannana.gif");
static ImageIcon cherry = new ImageIcon ("cherry.gif");
static ImageIcon grape = new ImageIcon ("grape.gif");
static ImageIcon orange = new ImageIcon ("orange.gif");
static ImageIcon lemon = new ImageIcon ("lemon.gif");
static ImageIcon plum = new ImageIcon ("plum.gif");
static ImageIcon pear = new ImageIcon ("apple.pear");
static ImageIcon backing = new ImageIcon ("backing.gif");
static ImageIcon apple = new ImageIcon ("apple.gif");

---

1.
you have 2 times same line of code:
static ImageIcon apple = new ImageIcon ("apple.gif");
delete one of this lines.

2.
getContentPane().setBackground(Color BLUE);
change with
getContentPane().setBackground(Color.BLUE);

3.new Memory().show();
.show() is obsolete, I'll try to fix that later.

4.
for (i=0;i<16;i++)
change with
for (int i=0;i<16;i++)

5.
for (index=0;index<16;i++)
change with
for (int index=0;index<16;index++)

6.
guessLabel.setText("Guesses"+String.value of (guesses));
change with
guessLabel.setText("Guesses"+String.valueOf (guesses));

That's few little mistakes. There are still lots of mistakes. I'll look deep in code to resolve other problems.

7.
newButton.doclick();
change with:
newButton.doClick();

8.
getContentPane().add(guessLabel,gridConstraints);
change with:
getContentPane().add(guessLabel,gridConstraints);

9.
getContentPane().add(newbutton.gridConstraints);
change with:
getContentPane().add(newButton,gridConstraints);

10.
getContentPane().add(exitButton.gridConstraints);
change with:
getContentPane().add(exitButton,gridConstraints);

11.
newButton.setEnable(true);
change with:
newButton.setEnabled(true);

12.
exitform (null);
change with
exitForm (null);

13.
public void actionperformed (ActionEvent e)
change with:
public void actionPerformed (ActionEvent e)

Now, I'll try to find problem with boxLabel

I guess this is a complete code:
