Sometimes we need to interrupt an executing thread at a specified point in time. For example, the thread that checks the sensor state every minute, and the rest of the time, the thread does not need to do anything. During this time, the thread does not need to use any of the computer's resources. After this time, and when the Java Virtual machine dispatches the thread, the thread continues to execute. To do

Simple use of Java transactions Java transactions are asked in some interviews. In the interview, the first thing we should answer is: The transaction can ensure the integrity and consistency of the data.

The Production and Consumption thread type is a good example of understanding multithreading. In fact, it should be accurate to say that it is the "producer-consumer-warehouse" model. when it leaves the warehouse, the producer and consumer model becomes unconvincing. For this model, the following points should be clarified: 1. The producer only produces when the warehouse is not full, and stops producing when the Warehouse is full. 2. Consumers can on

In the book "Java and Patterns" of Dr. Shanhong, this describes the singleton pattern:　　As an object's creation mode, Singleton mode ensures that a class has only one instance, and instantiates itself and provides this instance to the system as a whole. This class is called a singleton class. Structure of the Singleton patternthe characteristics of the singleton mode: A singleton class can have only one instance. The Singleton class

In the Java environment, the reflection mechanism allows a program to obtain a variety of its own definition information, such as properties and methods, that can also implement the ability to dynamically create objects of a class, change the contents of a property, or perform a specific method. So that Java has dynamic language characteristics, enhance the flexibility and portability of the program. the fu

A brief description: The use of Java NIO to develop network communication is relatively fast and aspect. Because he can listen to client connections without blocking, the event-based mechanism can be used in Java NiO for non-blocking communication when something new When registering, we only need to get new events through the event listening mechanism Simply put, there is a Selector in

object method is invoked. The Insider of dynamic binding: 1. The compiler examines the type and method names of object declarations to obtain all candidate methods. Try to comment out the test of the base class above, and then compile it.2. Overload resolution: The compiler examines the parameter types of the method invocation, selecting the only one from the candidate method (there will be implicit type conversions).If the compiler finds more than one or does not find it, the compiler will n
