    上面就是泡茶的步骤，我们开启两个线程，小王和老王来完成泡茶。

    1. public class TwoThreadPaoTea {
    3.     public static void main(String[] args) {
    4.         Thread t1 = new Thread(() -> {
    5.             System.out.println(Thread.currentThread().getName() + "：洗水壶");
    6.             sleep(1);
    7.             System.out.println(Thread.currentThread().getName() + "：烧开水");
    8.             sleep(5);
    9.         }, "老王");
    11.         Thread t2 = new Thread(() -> {
    12.             System.out.println(Thread.currentThread().getName() + "：洗茶壶");
    13.             sleep(1);
    14.             System.out.println(Thread.currentThread().getName() + "：洗茶杯");
    15.             sleep(2);
    16.             System.out.println(Thread.currentThread().getName() + "：拿茶叶");
    17.             sleep(1);
    18.             try {
    19.                 t1.join();
    20.             } catch (InterruptedException e) {
    21.                 e.printStackTrace();
    22.             }
    23.             System.out.println(Thread.currentThread().getName() + "：泡茶");
    24.         }, "小王");
    25.         t1.start();
    26.         t2.start();
    28.     }
    30.     public static void sleep(int i) {
    31.         try {
    32.             TimeUnit.SECONDS.sleep(i);
    33.         } catch (InterruptedException e) {
    34.             e.printStackTrace();
    35.         }
    36.     }
    37. }

    结果

    1. 老王：洗水壶
    2. 小王：洗茶壶
    3. 老王：烧开水
    4. 小王：洗茶杯
    5. 小王：拿茶叶
    6. 小王：泡茶
