Thread Synchronization in Java and Android

public class Main {

public static void main(String[] args) {

SynDemo d = new SynDemo();
Thread1 th1 = new Thread1(d);
Thread2 th2 = new Thread2(d);

th1.start();
th2.start();

}

}

class SynDemo {

// synchronized

synchronized void printNumber(String string) {
for (int i = 0; i < 2000; i++) {
// Log.i("" + string, String.valueOf(i));
System.out.println(string + " = " + String.valueOf(i));
}
}
}

class Thread1 extends Thread {
private SynDemo d;

public Thread1(SynDemo sDemo) {
d = sDemo;
}

@Override
public void run() {
super.run();
d.printNumber("Thread1");

private SynDemo d;

public Thread2(SynDemo sDemo) {
