原创 C++与Java变量声明与赋值的区别

C++中的变量区分声明与定义，声明仅仅告诉编译器某个类型的变量会被使用，而定义才会为变量分配内存。int i=10;(定义)extern int i;(声明)Java中，不区分变量的声明与定义，变量声明接着赋值后就可以使用。在循环内使用while(1){int i=0;}因为每次循环是相对独立的区域，所以不会产生命名冲突

原创 Java多态性的理解

先写一些，有时间补充完整首先要理解几个概念：1、对象与对象变量。举个一般书中常见的栗子：比如要构造一个Date类的对象，语法为new Date(),有基础人的都知道这叫通过构造器构造了一个Date类的对象（至于什么叫构造器，就请百度......）回归正题，通常，我们希望自己构造出的对象可以多次使用，所以一个东西去表示它，这时就出现了对象变量，将对象存放在对象变量中，语法为Da
