java 实例化线程（Thread）

        实例化Thread有两种方式:

        一种方法是extends Thread 类。重写 Thread 类的 run 方法。

public class TestThread extends Thread {
    public TestThread (String name){
    	super(name);
    }
    
    public void run(){
    	for(int i=0; i<100000; i++){
    		for(int k=0; k<200000000; k++);
    		System.out.println(this.getName()+":"+i);
    	}
    }
    
    public static void main(String [] args){
    	Thread thread1 = new TestThread("LOL");
    	Thread thread2 = new TestThread("Dota");
    	
    	thread1.start();
    	thread2.start();
    }
}

 另一种方法是implements Runnable接口 ，自己实现run()方法。然后用Thread的构造方法，实例化。

 

public class DoSomething implements Runnable {

	
	private String name;
	
	public DoSomething(String name){
		this.name = name;
	}
	
	@Override
	public void run() {
        for(int i=0; i<5; i++){
        	for(int k=0; k<100000000; k++);
        	System.out.println(name+":"+i);
        }		
	}

}

 

public class TestRunnable {
    public static void main(String [] args){
    	DoSomething dos1 = new DoSomething("LOL");
    	DoSomething dos2 = new DoSomething("Dota");
    	
    	Thread thread1 = new Thread(dos1);
    	Thread thtead2 = new Thread(dos2);
    	
    	thread1.start();
    	thtead2.start();
    }
}
