Answer 1

Thread

Answer 2

You need a multi-threaded application. There are quite a few options for how to run multiple threads at the same time. Simplest:

Thread thread1 = new Thread(new Runnable() {
    public void run() {
        while (....)
            ....
    }
});
Thread thread2 = new Thread(new Runable() {
    public void run() {
        while (....)
            ....
    }
});
thread1.start();
thread2.start();
