Two ways to open threads

/**

• Two ways to customize the execution unit
• Difference
• Runnable avoids the limitations of single inheritance
• Runnable resources can be shared independently
• How to find problems with multithreading
  1. Identify which code is multithreaded to run the code
  2. Identify what is shared data
  3. Identify which statements in multithreaded code are operations that share data

• Mode 1 Inherits Thread
• If you want to implement two windows to buy tickets,
• MyThread t0=new MyThread ();
  MyThread t1=new MyThread ();
  T0.start ();
  T1.start ();//200 tickets appear
  If adding static in front of the tick solves the problem but the life cycle is too long, use mode 2
