First, multi-threaded writing steps

1. Threading class Inherits Thread

2. Overriding the Run () method in a thread class

3. Create a thread object in the test class and start the thread with the start () method

How to Runnable interfaces

1. Thread class inheritance

2. Create a Thread object: Assuming that the thread class is runnable, use runnable myrunnable = new Myrunnable (), create the object, and then use the thread t = new thread (myrunnable);

3. Start the thread

Note: This method must create an object

The difference between a thread object calling start (), a method, and calling the run () method

1.run () only the main thread one execution path

2.start (): Multiple execution paths, the main thread and child threads are alternately executed in parallel

Methods for anonymous inner classes: Override the Run method directly in the test class

    New Thread () {            @Override            publicvoid  run () {                //  TODO auto-generated method Stubwhile                 (!  Teemo.isdead ()) {                    gareen.attack (Teemo);}}        ;        T1.start ();

Some common methods of threading

Priority is 1~10, 1 lowest, default priority is 5
