Inherit Thread class 1. Implementation description

By inheriting Thread and overriding its run (), the run method defines the tasks that need to be performed. The created subclass executes the thread method by calling the start () method.

2. Specific steps

1) define the UserThread class and inherit the Thread class

2) override the run () method
