intermediate cache variables in Java. Equivalent to: Tmp=j, J=j+1, j=tmp. So after the expression is finished, j=j, it will not change.2. Data type ConversionJava basic data types fall into three main categories: Boolean, character, numeric. The numerical type is also divided into floating-point and integral type.8 Basic types: Boolean, char, Byte, short, int, long, float, double.Corresponding wrapper classes: Boolean,character, Byte, short, Integer,

IntroductionThis tutorial is the help of understand about Java OOP's concepts with examples. Let's discuss about what is the features of Object oriented programming. Writing object-oriented programs involves creating classes, creating objects from those classes, and creating applications , which is stand-alone executable programs that use those objects. A class i

First, lightweight and heavyweight are relative concepts, mainly for the ease of use of the application framework and the service features provided.For example, EJB is a heavyweight framework, because itCodeIt also provides distributed and other complex functions.In contrast, spring is a lightweight framework, because it only requires common Java objects, and it provides only enough functions for Small and

The embodiment of thread safety 不可变：对象被构建完后，其外部可见状态永远不会改变绝对线程安全：不管运行环境如何，调用者都不需要任何额外的同步措施相对线程安全：Java语言中的大部分线程安全类，或通常意义所说的线程安全。其保证单独的操作是安全的，对于一些特定顺序的连续调用，则需要额外的同步措施线程兼容：Java语言中的大部分类（ArrayList,HashMap等），对象本身并不是线程安全的，但是可以通过在客户端使用同步措施来保证对象在并发环境下安全使用，线程对立：无论使用哪种同步措施都不能保证线程安全，例如Thread的suspend resume等 Thread-Safe Implementation methods: 互斥同步：是一种悲观的并发策略，多个线程并发访问共享数据时，保证共享数据在同一时刻只能被一个（或者是一些，使用信号量时）线程使用；临界区，互斥量，信号量都是
