## 1.实现Runnable接口 ##

public class ThreadDemo implements Runnable {
        private volatile String threadName;
    
        ThreadDemo( String name) {
            threadName = name;
            System.out.println("Creating " +  threadName );
        }
    
        @Override
        public void run() {
            System.out.println("线程名:"+threadName);
        }
    }

**测试类**

public class ThreadTest {
        public static void main(String[] args) {
            ThreadDemo T1 = new ThreadDemo("wyp");
            new Thread(T1).start();
            ThreadDemo T2 = new ThreadDemo("wj");
            new Thread(T2).start();
        }
    }

**Runnable是一个函数式接口所以可以直接使用lambda**

Runnable T3 = () -> {
                System.out.println("啊哈哈");
            };
            new Thread(T3).start();

**打印**

## 2.继承Thread类 ##

public class ThreadDemo extends Thread {
        public static void main(String[] args) {
            new ThreadDemo().start();
        }
    
        @Override
        public void run() {
            System.out.println("继承Thread");
        }
    }
