线程的实现方式
多线程的两种实现方式，第一种继承Thread类，第二种实现Runnable接口。
方式一（继承Thread类）：
Java代码
package com.demo.thread;
public class ThreadDemo1 extends Thread
{
private int count = 5;
// 只初始化一次
private static int threadCount = 0;
private int threadNumber = ++threadCount;
public ThreadDemo1()
{
System.out.println("Making" + threadNumber);
}
public void run()
{
while (true)
{
System.out.println("Thread" + threadNumber + "(" + count + ")");
if (--count == 0)
{
return;
}
}
}
public static void main(String[] args)
{
for (int i = 0; i < 5; i++)
{
new ThreadDemo1().start();
}
System.out.println("All threads started!");
}
}
方式二（实现Runnable接口）：
Java代码
package com.demo.thread;
public class ThreadDemo2 implements Runnable
{
private int count = 5;
private static int threadCount = 0;
private int threadNumber = ++threadCount;
public ThreadDemo2()
{
System.out.println("Making" + threadNumber);
}
public void run()
{
while (true)
{
System.out.println("Thread" + threadNumber + "(" + count + ")");
if (--count == 0)
{
return;
}
}
}
public static void main(String[] args)
{
for (int i = 0; i < 5; i++)
{
ThreadDemo2 td = new ThreadDemo2();
new Thread(td).start();
}
System.out.println("All Threads started!");
}
}
补充：软件开发 , Java ,
