independent of each other, and it is easier to share data and improve the efficiency and performance of the program through the way the art of war executes. Threads VS Process1 , the thread is divided by a process, and the thread belongs to a process. 2 , a process is a dynamic form of the program, is CPU , memory and other resources occupy the basic unit, and threads are not independent of the possession

after entering this state, and must be called notify () or Notifyall () method, the thread enters waiting.3. Case explanation案例：用案例解释线程的六种运行状态,其中Pig类实现Runnable接口，逻辑是打印当前运行的线程信息，每隔一秒打印一次。在Main方法中启动十个Pig线程设置相应的线程优先级别，并且将初始的线程状态保存到线程状态数组中，在运行的过程判断当前线程状态和初始状态是否相同，如果不同则打印当前线程的信息保存到日志文件中。 1 class Pig implements Runnable {2 3 @Override 4 public void Run () {5 for (int i = 0; i Partial execution results are as follows:Analysis of the above partial execution results shows that when the pig thread sleeps
