For example:Consider you have iPhone, Samsung and Sony devices and you want to represent them in JAVA. To do that you first need to find out what can be the blueprint behind these devices. And here blueprint can be a Mobile because they all are a type of Mobile. So Mobile is a cl...
an object is created, occupying memory space. Each object has its own state (values of instance variables) and behavior (methods defined in the class). Using the earlier example, an object could be an instance of the

注意:Class对象由JVM自动创建,编程人员无法通过API直接new对象. 对象克隆: (1) 概念:Object.clone():创建当前对象的副本;前提条件:实现的Cloneable接口 (2) 意义:简化对象的拷贝,通过JDK平台统一一个对象副本的创建方式. (3) super.clone():是java本地的方法,通过虚拟机JVM内部机制自动完成对象内容的复制。
In the above example, we have created an object output stream named objStream that is linked with the file output stream named fileStream. Methods of ObjectOutputStream The ObjectOutputStream class provides implementations for different methods present in the OutputStream class. write() Method write...
