Java中线程实现的两种方式例程

1. 继承Thread

package com.sunplusedu;

public class JavaTest {
    public static void main(String args[]){
        new MyThread().start();
        int i = 10;
        for(i = 10; i > 0; i--){
            System.out.println("in the main "+i);
            try {
                Thread.currentThread();
                Thread.sleep(1*1000);
            } catch (Exception e) {
                // TODO: handle exception
                System.out.println("main Exception");
            }
        }        
    }

}

class MyThread extends Thread{
    
    public void run(){
        int i = 10;
        for(i = 10; i > 0; i--){
            System.out.println("in the Thead"+i);
            try {
                Thread.currentThread();
                Thread.sleep(1 * 1000);
            } catch (Exception e) {
                // TODO: handle exception
                System.out.println("MyThread Exception ");
            }
        }
    }
}

 

2.接口Runnable实现

package com.sunplusedu;


public class JavaRunable {
    public static void main(String args[]){        
        int i = 0;
        MyThread mt = new MyThread();
        new Thread(mt).start();
        for(i = 0; i <= 10; i++){
            System.out.println("in the Main " + i);
            //Java中延时方式
            try {
                Thread.currentThread();
                Thread.sleep(1*1000);
            } catch (Exception e) {
                // TODO: handle exception
                System.out.println("Main Exception");
            }
        }
    
    }
}

class MyThread implements Runnable{
    //复写时的方法访问权限不能比接口中的权限低,所以run方法的要权限应该为public 
    public void run(){
        int i = 0;
        for(i = 0; i <= 10; i++){
            System.out.println("in the MyThread "+i);
            try {
                Thread.currentThread();
                Thread.sleep(1*1000);
            } catch (Exception e) {
                // TODO: handle exception
                System.out.println("Thread Exception");
            }
        }
    }
    
}
