java多线程想能够交替打印奇数和偶数，却只能打印0和1而已，求大神帮忙解决！

public class Edd extends Thread {

private Object object;
private int n = 0;

public Edd(Object object) {
this.object = object;
//System.out.println("EddThread----" + object.toString());
}

@Override
public void run() {
// TODO Auto-generated method stub

while (n <= 10) {
synchronized (object) {
if (n % 2 == 0) {
System.out.println("EddThread----" + n++);
if(n==10){
Thread.interrupted();
}
} else {
object.notifyAll();
try {
object.wait(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

}
super.run();
}
}


public class Odd extends Thread {

private Object object;
private int n = 1;

public Odd(Object object) {
this.object = object;
//System.out.println("OddThread----" + object.toString());
}

@Override
public void run() {
// TODO Auto-generated method stub

while (n <= 10) {
synchronized (object) {
if (n % 2 != 0) {
System.out.println("OddThread----" + n++);
if(n==9){
Thread.interrupted();
}
} else {
object.notifyAll();
try {
object.wait(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
super.run();
}
}


public class ExpThread {
public static Object object;
public static void main(String[] args){

object = new Object();
Edd eddThread = new Edd(object);
Odd oddThread = new Odd(object);
eddThread.start();
oddThread.start();
}
}

对N加锁，两个线程轮流去获取N的锁，然后打印。
