Pause program with Timer

Question

I need to use it to wait 2 minutes before executing a method. I have researched and can’t find anything clear enough to help me.

I’ve used the Thread.sleep() the more he locks the thread all of it, and that’s not what I’m after. Thank you to those who help.

Answer 1

That should be simple.

Timer timer;

public Executar(int segundos) {
    timer = new Timer();
    timer.schedule(new MinhaFuncao(), segundos*1000);
}

class MinhaFuncao extends TimerTask {
    public void run() {
        //faz tudo que precisa fazer aqui
        timer.cancel(); //Termina a task
    }
}

Hence you call the run by passing 120 seconds to the method.

OBS: this example uses the java.util.Timer timer http://docs.oracle.com/javase/7/docs/api/java/util/Timer.html

If you are going to use javax.swing.Timer doc: http://docs.oracle.com/javase/7/docs/api/javax/swing/Timer.html

Then you must do so

Timer timer;

int delay = 120*1000; //2 minutos

ActionListener tarefaAgendada = new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        //faz o que tem que fazer
    }
};

timer = new Timer(delay, taskPerformer);
timer.setRepeats(false); //faz rodar apenas 1 vez, sem isso ele ficar invocando a action de 2 em 2 minutos
timer.start(); //inicia a task
