I have the following task:
Timer tempovolta1 = new Timer();
TimerTask tarefavolta1 = new TimerTask() {
@Override
public void run() {
jButton1.setBackground(Color.BLUE);
}
};
I want to call you several times:
tempo1.schedule(tarefa1, 2000 );
After a while I'll call her and give ERROR :
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Task already scheduled or canceled
So I realized that you really want or need to use the Swing timer.
Set a constant for example
private static final int TIMER_DELAY = 50;
Your Timer
new javax.swing.Timer(TIMER_DELAY, new ActionListener() {
public void actionPerformed(ActionEvent e) {
loopTeste();
}
}).start();
And your method
public void loopTeste() {
button.setLocation(button.getLocation().x + 5, button.getLocation().y);
getContentPane().repaint();
}
