在Java中编写程序：创建一个线程以模拟进程的就绪状态,执行状态和阻塞状态之间的转换。

在Java中编写程序：创建一个线程以模拟进程的就绪状态,执行状态和阻塞状态之间的转换。

boolean running = true;
static final Object LOCK = new Object();
int x = 0;
Runnable r1 = new Runnable() { //Task run in Main Thread
public void run() {

while(running) {

syncronized(LOCK) {
System.out.println("Main task starts running now");

while(running) {

System.out.println("Main task is to do some work with x);
x ++;

System.out.println("Main task makes x self added");

System.out.println("After work has done , Main task is going to be blocked soon");

LOCK.wait();

System.out.println("Main task is notifed and it resumes to run");

}

System.out.println("Main thread is going to end after FLAG running turned false");

}

}
Runnable r2 = new Runnable() { //The task cooperate with Main task
public void run() {

syncronized(LOCK) {

while(true) {

if(x < 100) {

running = true;
LOCK.notifyAll();
} else {

running = false;

LOCK.notifyAll();

break;

}
Thread.sleep(300);

}

}

}

}

public void main() {
Thread t1 = new Thread(r1);

Thread t2 = new Thread(r2);

t1.start();
// After this(t1.start()) called , t1 thread is ready until it starts running, but it's a very short // time for us.
t2.start();

}

随手写了些，3种状态应该很清楚了。 这个地方打代码格式对不齐，这个也没办法了。
