java线程的经典代码

package threadgroup;

class ThreadDemo3 extends Thread {

private String name;

private int delay;

public ThreadDemo3(String sname, int i_delay) {

name = sname;

delay = i_delay;

}

public void run() {

try {

sleep(delay);

} catch (InterruptedException e) {

}

System.out.println(“多线程测试！\n” + name + “\n” + delay);

}

}

public class testMyThread {

public static void main(String[] args) {

ThreadDemo3 th1,th2,th3;

th1 = new ThreadDemo3(“线程1”, (int) (Math.random() * 900));

th2 = new ThreadDemo3(“线程2”, (int) (Math.random() * 900));

th3 = new ThreadDemo3(“线程3”, (int) (Math.random() * 900));

th1.start();

th2.start();

th3.start();

}

}

package threadgroup;

public class threadDemo {

public static void main(String[] args) {

Thread t = Thread.currentThread();

t.setName(“你好吗？”);

System.out.println(“正在进行的Thread是：” + t);

try {

for (int i = 0; i 5; i++) {

System.out.println(“我不叫穆继超” + i);

Thread.sleep(3000);

}

} catch (Exception e) {

// TODO: handle exception

System.out.println(“Thread has wrong” + e.getMessage());

}

}

}

package threadgroup;

public class threadDemo2 implements Runnable {

public threadDemo2() {

Thread t1 = Thread.currentThread();

t1.setName(“第一个主进程”);

System.out.println(“正在运行” + t1);

Thread t2 = new Thread(this, “”);

System.out.println(“在创建一个进程”);

t2.start();

try {

System.out.println(“使他进入第一个睡眠状态”);

Thread.sleep(2000);

} catch (InterruptedException e) {

System.out.println(“Thread has wrong” + e.getMessage());

}

System.out.println(“退出第一个进程”);

}

public void run() {

try {

for (int i = 0; i 5; i++) {

System.out.println(“进程” + i);

Thread.sleep(3000);

}

} catch (InterruptedException e) {

// TODO: handle exception

System.out.println(“Thread has wrong” + e.getMessage());

}

System.out.println(“退出第二个进程”);

}

public static void main(String[] args) {

new threadDemo2();

}

}

给段最简单的java代码 让我新手看一下

最简单的java代码肯定就是这个了，如下：

public class MyFirstApp

{

public static void main(String[] args)

{

System.out.print(“Hello world”);

}

}

“hello world”就是应该是所有学java的新手看的第一个代码了。如果是零基础的新手朋友们可以来我们的java实验班试听，有免费的试听课程帮助学习java必备基础知识，有助教老师为零基础的人提供个人学习方案，学习完成后有考评团进行专业测试，帮助测评学员是否适合继续学习java，15天内免费帮助来报名体验实验班的新手快速入门java，更好的学习java！

一个简单的Java程序代码？

package com.zpp;public class Charge {

public static void main(String [] args) {

if(args.length ==0) {

System.out.println(“parameter error!”);

System.out.println(“java com.zpp.Charge [int]”);

return;

}

int min = Integer.parseInt(args[0]);

double money = 0.0;

if (min = 0) {

money =0.0;

System.out.println(“not money”);

} else if (min = 60) {

money = 2.0;

} else {

money = 2.0 + (min – 60) * 0.01;

}

System.out.println(“please pay: ” + money);

}

} 编译：javac -d . Charge.java运行：java com.zpp.Charge 111

说明

1 “@”后面的数字越大，重复次数越多

2把上面代码复制，在计算机上保存为.txt文本文件，再改名为 .imy 文件

3 imy 放到手机里的Audio文件夹

4写短信(不是彩信) 写短信时, 插入铃声对象(自定义铃声对象，就是刚才放在audio 里的imy 文件) 并发送, 对方只要是存在这个芯片漏洞，那么则会产生上述所说效果.
