本文实例讲述了Java实现在不同线程中运行的代码。分享给大家供大家参考，具体如下：
start()方法开始为一个线程分配CPU时间，这导致对run()方法的调用。
代码1
package Threads;
/**
* Created by Frank
*/
public class ThreadsDemo1 extends Thread {
private String msg;
private int count;
public ThreadsDemo1(final String msg, int n) {
this.msg = msg;
count = n;
setName(msg + " runner Thread");
}
public void run() {
while (count-- > 0) {
System.out.println(msg);
try {
Thread.sleep(100);
} catch (InterruptedException e) {
return;
}
}
System.out.println(msg + " all done.");
}
public static void main(String[] args) {
new ThreadsDemo1("Hello from X", 10).start();
new ThreadsDemo1("Hello from Y", 15).start();
}
}
代码2：
package Threads;
/**
* Created by Frank
*/
public class ThreadsDemo2 implements Runnable {
private String msg;
private Thread t;
private int count;
public static void main(String[] args) {
new ThreadsDemo2("Hello from X", 10);
new ThreadsDemo2("Hello from Y", 15);
}
public ThreadsDemo2(String m, int n) {
this.msg = m;
count = n;
t = new Thread(this);
t.setName(msg + "runner Thread");
t.start();
}
public void run() {
while (count-- > 0) {
System.out.println(msg);
try {
Thread.sleep(100);
} catch (InterruptedException e) {
return;
}
}
System.out.println(msg + " all done.");
}
}
代码3：
package Threads;
/**
* Created by Frank
*/
public class ThreadsDemo3 {
private int count;
public static void main(String[] args) {
new ThreadsDemo3("Hello from X", 10);
new ThreadsDemo3("Hello from Y", 15);
}
public ThreadsDemo3(final String msg, int n) {
this.count = n;
Thread t = new Thread(new Runnable() {
public void run() {
while (count-- > 0) {
System.out.println(msg);
try {
Thread.sleep(100);
} catch (InterruptedException e) {
return;
}
}
System.out.println(msg + " all done.");
}
});
t.setName(msg + " runner Thread");
t.start();
}
}
