多线程学习1-创建线程

实例代码：

class ThreadDemo{public static void main(String [] args){System.out.println(Thread.currentThread().getName()+" run...");/*创建线程，并启动*/Thread thread0 = new Thread();thread0.start();/*线程创建方法一：重写子类*/Thread thread1 = new Thread(){@Override public void run(){//codeSystem.out.println(Thread.currentThread().getName()+" run...");}};thread1.start();/*线程创建方法二：重写Runnable（更能体现面对对象思想）*/Thread thread2 = new Thread(new Runnable(){@Overridepublic void run(){//codeSystem.out.println(Thread.currentThread().getName()+" run...");}});thread2.start();/*思考题：打印结果？*/Thread thread3 = new Thread(new Runnable(){@Overridepublic void run(){//codeSystem.out.println(Thread.currentThread().getName()+"_Runnable() run...");}}){@Overridepublic void run(){//codeSystem.out.println(Thread.currentThread().getName()+"_subRun() run...");}};thread3.start();}}

测试结果：

main run...Thread-1 run...Thread-2 run...Thread-3_subRun() run...
