Textbook learning content summary

Chapter 12: Java Multithreading Mechanism

• process and thread
• Operating system and process: A process is a dynamic execution of a program.
• process and thread
  • A thread is a smaller unit of execution than a process.
  • A process can spawn multiple threads during its execution.
• Threads in Java
• main thread (main thread)
• Thread state and life cycle
  • new
  • run
  • interrupt
  • die
• Thread scheduling and priority
• Thread class and thread creation
  
• Use a subclass of Thread
• Use the Thread class
• The relationship between the target object and the thread
  • The target object and the thread are completely decoupledString name=Thread.currentThread().getName();
  • Target object composition thread (weak coupling)Thread.currentThread();
• About the number of times the run method starts
• Common methods of threading
• start()
• run()
• sleep (int millsecond)

• isAlive

  Thread thread = new Thread(target);
  thread.start();

• currentThread()
• interrupt()
• thread synchronization
• coordinating synchronized threads
• thread unionB.join();
• GUI thread
• timer thread

• Daemon threadthread.setDaemon(true);
