使用Runnable创建线程
package com.cky.runner; /**
* Created by chenkaiyang on 2017/12/2.
*/
public class MyRunnable implements Runnable{
@Override
public void run() {
System.out.println("运行中");
}
}
test类
package com.cky.test; import com.cky.runner.MyRunnable; /**
* Created by chenkaiyang on 2017/12/2.
*/
public class Test {
public static void main(String[] args){
MyRunnable myRunnable = new MyRunnable();
Thread thread = new Thread(myRunnable);
thread.start();
System.out.println("运行结束"); }
}

运行结束
运行中 Process finished with exit code 0
因为java是单根集继承，不支持多继承，为了改变这个限制，使用runnable接口实现多线程
注：Thread类也实现了Runnerable接口，那说明了构造函数不仅仅可以传入runnable接口对象，也可以传递Thread对象，这样做完全可以将一个Thread对象的run方法交给其他线程调用
