equals 1 milliseconds). However, the Java virtual machines on most operating system platforms are not accurate to nanoseconds, so if you set a nanosecond for sleep, the Java virtual machine takes milliseconds closest to that value. 2. When using the Sleep method, you must use throws or try{...} Catch{...}. Because the Run method cannot use throws, you can only use try{...} Catch{...}. When a

Java Thread Series (ii) Threads state One, five states of threads New state: A new Thread object has been created and has not been started. Ready state (Runnable): Also known as the operational state. After the thread object is created, other threads call the object's start () method. The state of the

thread has been interrupted. The interrupted status of the thread is cleared by ThisMethod.//test if the front thread is interrupted, calling this method clears the interrupt state. In other words,if ThisMethod were to being called twice in succession,The second call wouldreturn false(unless the current

overridden to implement the main function of this thread, This is also the way to implement the Runnable interface. Second, a class should be inherited when they need to be strengthened or modified. Therefore, if it is not necessary to rewrite other methods of the thread class, it is best to implement the Runnable interface in this case. three, in the disconnection processThe

Termination and thread interruption of java threads, and termination interruption of java threads About thread termination: 1. Generally, the thread enters the dead state after execution is completed, and the thread is terminated

Java multithreading -- let the main thread wait for the sub-thread to finish executing, java Multithreading When using Java multi-threaded programming, the main thread often needs to wait until the sub-

The blocking and wakeup of threads is a key point in multithreaded concurrency, and when the number of threads reaches a large order of magnitude, concurrency can lead to a lot of hidden problems. How to properly pause a thread, and then how to resume at a required point in time, requires careful consideration of the details. In the history of Java, the suspend (), resume () method was used to wake up the

Interrupt () While one thread is running, another thread can interrupt it by invoking its corresponding Thread object's interrupt () method: public void interrupt () this method simply

1. Introduction to Thread Priority The range of thread priorities in Java is 1~10, and the default priority is 5. High priority threads take precedence over low priority threads. There are two kinds of threads in Java: The user thread and the daemon

the thread pool is closed or the task throws a runtimeexception.This shows that the basic principle of the thread pool is actually very simple, nothing more than pre-boot some threads, thread into the dead loop state, each time from the task queue to get a task to execute, until the thread pool is closed. If a

Java foreground thread and background thread Last blog in the Main () method, after creating and starting four new threads, the code in the main () method completes, at which point the method ends and the main thread ends. The results of the program can be seen, although the main
