package cn.iktz.thread.demo;

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class LockTest2 {

public static void main(String[] args) {
new LockTest2().init();
}

private void init() {
Outputer outputer = new Outputer();
new Thread(new MyRunnable(outputer, "1234567")).start();
new Thread(new MyRunnable(outputer, "abcdefg")).start();
}
}
class Outputer {
Lock lock = new ReentrantLock();

public void output(String name) {
int len = name.length();
lock.lock();
try {
for (int i = 0; i < len; i++) {
System.out.print(name.charAt(i));
}
System.out.println();
} finally {
lock.unlock();
}
}
}
class MyRunnable implements Runnable {
private Outputer outputer;
private String name;

public MyRunnable(Outputer outputer, String name) {
this.outputer = outputer;
this.name = name;
}
@Override
public void run() {
while (true) {
outputer.output(name);
}
}
}
