Remeber which label in array was clicked?

I have an array of LABELS. I also have a mouselistener and I need to know how to remember which label was clicked and change the background icon for it.

any ideas????

One method would be to use a JButton's, with no borders and attach a listener to each.

Can you show me how to do an array of labels (or jlabels)? You've just givven me an idea, thanks.

Do you want an array such as:-

JLabel labelArray[] = new JLabel[5];
for(int i=0;i<labelArray.length;i++) {
 labelArray[i] = new JLabel();
}

or a graphical array of labels, in which case you'll have to become familiar with Java's layout managers, e.g. GridLayout.

This is one way to do it although probably not the most efficient.

In a for loop add an actionListener to each label in your array. Create a final int variable to track the index number of your array. In the mouse_clicked method use both the index int and the ActionEvent e as parameters

for(int i=0;i,array.length;i++){
final int index = i;
array.addMouseListener(Listener type){
array_Mouse_Clicked(index, e)etc....

Set up your array_Mouse_Clicked method like...

public void array_Mouse_Clicked(int index, ActionEvent e){
Actions to be performed;
}
