Java多线程打印ABABABAB

思路：多线程打印AB，就需要两个线程类，一个线程负责打印一个，调用wait()和notify()方法去控制线程间的通信

package thread;

public class PrintAB {

//声明boolean变量用来控制打印

private boolean flag = false;

//打印A

public synchronized void printA(){
while(flag){
try {
wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
System.out.println("A");
flag = true;
notify();

}

//打印A

public synchronized void printB(){
while(!flag){
try {
wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
System.out.println("B");
flag = false;
notify();

}

//定义打印A的线程类

class A implements Runnable{


@Override
public void run() {
// TODO Auto-generated method stub
for(int i=0;i<10;i++){
printA();
}
}
}

//定义打印B的线程类

class B implements Runnable{


@Override
public void run() {
// TODO Auto-generated method stub
for(int i=1;i<10;i++){
printB();
}
}
}

public static void main(String[] args) {
PrintAB p = new PrintAB();
A a = p.new A();
B b = p.new B();
Thread t = null;

t = new Thread(a);
t.start();
t = new Thread(b);
t.start();

}
}
