一.线程的创建和启动
package com.gatsby.test;
class MyThread extends Thread {
// 覆写run()方法,作为线程 的操作主体
@Override
public void run() {
// TODO Auto-generated method stub
super.run();
for (int i = 1; i < 13; i++) {
System.out.println( " ThreagetId->" + getId() + " " + i);
}
}
}
public class RunnableDemo01 {
public static void main(String[] args) {
new MyThread().start();
// 实例化对象
MyThread myThread2 = new MyThread();
//调用线程主体
myThread2.start();
}
}
程序运行：
ThreagetId->11 1 ThreagetId->10 1 ThreagetId->10 2 ThreagetId->10 3 ThreagetId->10 4 ThreagetId->11 2 ThreagetId->10 5 ThreagetId->10 6 ThreagetId->10 7 ThreagetId->10 8 ThreagetId->11 3 ThreagetId->10 9 ThreagetId->10 10 ThreagetId->10 11 ThreagetId->10 12
package com.gatsby.test;
//通过实现Runnable接口来创建线程类
class MyRunnable implements Runnable{
// run方法同样是线程执行体
@Override
public void run() {
// TODO Auto-generated method stub
for (int i = 1; i < 13; i++) {
System.out.println( " ThreagetId->" +Thread.currentThread().getId() + " " + i);
}
}
}public class RunnableDemo02 {
public static void main(String[] args) {
// TODO Auto-generated method stub
MyRunnable myRunnable = new MyRunnable();
new Thread(myRunnable).start();
}
}
