When I click the button, I hope the background of the JButton will change its color. When I try to compile, an error appears
class, interface, or enum expected
Anyone can help me to figure out what's the problem?
@Override
public void actionPerformed(ActionEvent e) {
count ++;
JButton b = (JButton) e.getSource();
boolean BlackTurn = true;
for(int i = 0; i < rows; i++) {
for(int j = 0; j < column; j++) {
if(b == gameBoard[i][j] && gameBoard[i][j].getBackground() == Color.green) {
gameBoard[i][j].setBackground(Color.black);
}
}
}
}
This is most probably a problem of missing curly bracket or missing semicolon:
the error message you get refers to some missing (understand incorrect) class
(or interface
, or enum
) declaration.
If you were to post the whole content of the class declaration enclosing that method you showed us, I'm pretty sure we could find that missing character in a matter of seconds ;)
Also, since I'm at it, I prefer to use Color.GREEN
(and Color.BLACK
, Color.RED
, etc.) instead of Color.green
, because these aliases respect the convention that states that constants must be upper-case.
