求题 JAVA程序设计

//打印奇数的线程
public class OddCount extends Thread {
private Byte lock;//使用一个Byte作为锁
public OddCount(Byte lock){
this.lock = lock;
}
@Override
public void run() {
// TODO Auto-generated method stub
int count = 1;//需要打印的数
synchronized(lock){
try {
//由于要先打印偶数，所以打印奇数的线程线程开始时先等待
while(true){
lock.wait();
//打印10个奇数
System.out.println("打印10个奇数");
for(int i=0;i<10;i++){
System.out.print(count+" ");
count = count + 2;
}
System.out.println();
if(count>100) break;
lock.notify();//打印完毕后通知等待的线程行动
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
//打印偶数的线程
public class EvenCount extends Thread {
private Byte lock;//同奇数打印类的定义
public EvenCount(Byte lock){
this.lock = lock;
}
@Override
public void run() {
int count = 0;
synchronized(lock){
try {
while(true){
//打印操作
System.out.println("打印10个偶数");
for(int i=0;i<10;i++){
System.out.print(count+" ");
count = count + 2;
}
System.out.println();
if(count>100)break;
lock.notify();//通知等待的线程
lock.wait();//本线程进入等待
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}

//主函数
public class Main {
public static void main(String[] args) {
Byte lock = 0;//这个Byte作为锁来使用，将这个Byte分别传入两个线程

OddCount odd = new OddCount(lock);
EvenCount even = new EvenCount(lock);
//启动两个线程
odd.start();
even.start();
}
}
结果如下：
打印10个偶数
0 2 4 6 8 10 12 14 16 18
打印10个奇数
1 3 5 7 9 11 13 15 17 19

都是有界面的，写界面不难 就是很麻烦。。。我自己写的 都是可以直接运行的，有什么问题可以再问我。。。
