lambda表达式

public class Test {

    public  static void  main(String[] args){

        //通过lambda表达式实现
        new Thread(
                ()-> System.out.println("this is test1" )
        ).start();

        //接口和实现类（匿名内部类）实现
        new Thread(new Runnable() {
            @Override
            public void run() {
                System.out.println("this is test2" );
            }
        }).start();

    }
