Java多線程Thread常用方法

標籤：class   rri   執行   extends   star   set   static   停止   ati   

• getName():擷取此線程的名字
• setName():設定此線程的名字
• currentThread()：靜態，調取當前的線程
• run():子線程要執行的代碼放入run()方法中
• start()：啟動線程並執行相應的run()方法

package com.yyx.test;public class TestThread {    public static void main(String[] args) {        ThreadDemo thread1 = new ThreadDemo();        thread1.setName("線程一");        ThreadDemo thread2 = new ThreadDemo();        thread2.setName("線程二");        thread1.start();        thread2.start();    }}class ThreadDemo extends Thread {    @Override    public void run() {        for (int i = 1; i <= 20; i++) {            System.out.println(Thread.currentThread().getName() + ":" + i);        }    }}

•  join():在A線程中調用B線程的join()方法，表示：當執行到此方法，A線程停止執行，直至B線程執行完畢
•  sleep(long l):顯式的讓當前線程睡眠l毫秒

package com.yyx.test;public class TestThread {    public static void main(String[] args) {        ThreadDemo thread = new ThreadDemo();        thread.setName("線程一");        thread.start();        for(int j=1;j<=20;j++) {            Thread.currentThread().setName("主線程");            System.out.println(Thread.currentThread().getName() + ":" + j);            if(j==10) {                try {                    thread.join();                } catch (InterruptedException e) {                    e.printStackTrace();                }                            }                    }    }}class ThreadDemo extends Thread {    @Override    public void run() {        for (int i = 1; i <= 20; i++) {            System.out.println(Thread.currentThread().getName() + ":" + i);            try {                Thread.sleep(1000);            } catch (InterruptedException e) {                e.printStackTrace();            }        }    }}
