本文介绍了两种在Java中创建和运行线程的方法：通过继承Thread类和实现Runnable接口。详细展示了代码示例，包括如何启动线程，使用for循环进行计数，并利用Thread.sleep()方法实现线程延时。

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");
            }
        }
    }

}
