java線程的經典代碼

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(“多線程測試！\n” + name + “\n” + delay);

}

}

public class testMyThread {

public static void main(String[] args) {

ThreadDemo3 th1,th2,th3;

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

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

th3 = new ThreadDemo3(“線程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(“你好嗎？”);

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

try {

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

System.out.println(“我不叫穆繼超” + 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(“第一個主進程”);

System.out.println(“正在運行” + t1);

Thread t2 = new Thread(this, “”);

System.out.println(“在創建一個進程”);

t2.start();

try {

System.out.println(“使他進入第一個睡眠狀態”);

Thread.sleep(2000);

} catch (InterruptedException e) {

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

}

System.out.println(“退出第一個進程”);

}

public void run() {

try {

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

System.out.println(“進程” + i);

Thread.sleep(3000);

}

} catch (InterruptedException e) {

// TODO: handle exception

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

}

System.out.println(“退出第二個進程”);

}

public static void main(String[] args) {

new threadDemo2();

}

}

給段最簡單的java代碼 讓我新手看一下

最簡單的java代碼肯定就是這個了，如下：

public class MyFirstApp

{

public static void main(String[] args)

{

System.out.print(“Hello world”);

}

}

「hello world」就是應該是所有學java的新手看的第一個代碼了。如果是零基礎的新手朋友們可以來我們的java實驗班試聽，有免費的試聽課程幫助學習java必備基礎知識，有助教老師為零基礎的人提供個人學習方案，學習完成後有考評團進行專業測試，幫助測評學員是否適合繼續學習java，15天內免費幫助來報名體驗實驗班的新手快速入門java，更好的學習java！

一個簡單的Java程序代碼？

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);

}

} 編譯：javac -d . Charge.java運行：java com.zpp.Charge 111

說明

1 「@」後面的數字越大，重複次數越多

2把上面代碼複製，在計算機上保存為.txt文本文件，再改名為 .imy 文件

3 imy 放到手機里的Audio文件夾

4寫簡訊(不是彩信) 寫簡訊時, 插入鈴聲對象(自定義鈴聲對象，就是剛才放在audio 里的imy 文件) 並發送, 對方只要是存在這個晶元漏洞，那麼則會產生上述所說效果.
