Java 多线程：推荐方式一：🚀启动两个线程

🚀启动两个线程

• 调用 start() 才会真正运行。
• 千万别直接调 run()——
• 那只是普通方法调用，不会开新线程。

TestThread.java

• RunnableDemo R1 = new RunnableDemo(Thread-1);
• R1.start();
• RunnableDemo R2 = new RunnableDemo(Thread-2);
• R2.start();

• Creating Thread-1
• Starting Thread-1
• Creating Thread-2
• Starting Thread-2
• Running Thread-1
• Thread: Thread-1, 4
• Running Thread-2
• Thread: Thread-2, 4
• Thread: Thread-1, 3
• Thread: Thread-2, 3
• Thread Thread-1 exiting.
• Thread Thread-2 exiting.
