new Thread(){代碼…}.start();

new Thread(new Runnable(){代碼…}).start();

例子1:

匿名內部類的格式：

　　new 類名或者接口名() {

　　　　重寫方法;

　　};

本質：是該類或者接口的子類對象。

package com.test;

public class ThreadTest {

    public static void main(String[] args) {
        /**繼承Thread類來實現多線程*/
        new Thread() {
            public void run() {
                
 
for (int x = 0; x < 10; x++) {
                    System.out.println(Thread.currentThread().getName() + ":"
                            + x);
                }
            }
        }.start();

        /**實現Runnable接口來實現多線程*/
        new Thread(new Runnable() {
            @Override
            public
 
 void run() {
                for (int x = 0; x < 10; x++) {
                    System.out.println(Thread.currentThread().getName() + ":"
                            + x);
                }
            }
        }) {
        }.start();

        /**更有難度的*/
        new Thread(new Runnable() {
            @Override
            
 
public void run() {
                for (int x = 0; x < 100; x++) {
                    System.out.println("hello" + ":" + x);
                }
            }
        }) {
            public void run() {
                for (int x = 0; x < 10; x++) {
                    System.out.println("world" + ":" + x);
                }
            }
        }.start();
    }

}
