arrives or an event that the thread is waiting for occurs, the thread returns to a "running" state. Threads that are in a "timed wait" state and "wait" state cannot use it even if the processor is available. When a thread in a "running" state waits for another thread to perform a task, if it provides an optional waiting period, the thread enters a "timed wait" state. When another thread notifies the thread, or when the timed time period arrives (whic

Examples of services provided are the transmission of text. When the text is sent to the frontend node, it delegates the backend node, backend performs the transformation task, and returns the

multiple abstractions, define and implement a template method, and place the steps in this detailed method. Deferred to child class implementation. Subclasses can change the mutable parts of a parent class, but cannot change the top-level logic represented by a template method.15. The Observer pattern (Observer) defines a one-to-many dependency between objects, and when an object's state changes, all objects that depend on it are notified and actively updated by themselves. The separation betwe

Interaction with the user is the main role of Java, but also the reason Java is attractive, users can use the mouse and Java applet Program dialog. Let's look at the example that responds to the mouse: //Mouse.java import java.awt.*; import java.applet.*; public class Mouse extends Applet { 　String text=""; 　public vo

Deadlock:In the case of multi-threaded contention using shared resources. There is a possibility of a deadlock. For example, when a thread waits for a lock that is held by one of the threads. The thread may be waiting for the lock held by the first thread. At this time These two threads are stuck in endless mutual wait states. Such a situation is called a deadlock.The four necessary conditions for creating a deadlock:1, mutually exclusion conditions.T

amount of space memory. When the request arrives, the buffer pool assigns an idle thread to the request, runs the request into the thread, and processes it. When a predesigned thread is running, a prefab thread is not enough, the thread pool can create a certain number of new threads to handle more requests. When the system compares space, you can also remove a part of the thread that is inactive.The advantage of this is that, on the one hand, the system resource overhead of frequently creating
