Java定义一个圆类,属性为半径

importjava.util.Scanner;publicclassPoint{privatedoublex;privatedoubley;publicPoint(){this(0,0);}publ

就是类里面定义的一个字符串,数值,list,map等这样的一个变量或者常量/***这是Manager类*/publicclassManager{Stringusername="张三";//定义Mana

classCircle{\x09privatedoubler;\x09publicvoidsetR(doubler)\x09{\x09\x09this.r=r;\x09}\x09publicdoubl

邮箱有不,做好了发你再问：lmyzai@谢谢你了急用sina.com再答：算了直接上传给你

#include#includeusingnamespacestd;classCircle{doubler,Area,Circumference;public:Circle(doublea=0);Ci

#include"string.h"#include"iostream.h"classcomplex{private:floatx,y;public:complex(floatx,floaty){th

一个是类的方法（也叫动态属性）和属性（静态属性）,通过类名来访问一个是对象的方法和属性,需要通过一个实例来访问.静态属性程序一加载时就初始化存放在栈中实例属性需要实例化后才加载存放在堆中

//Complex.hclassComplex{private:floatReal;floatImag;public:Complex();Complex(floatRl,floatIm);Comple

publicclassTest{\x05publicstaticvoidmain(String[]args){\x05\x05Rectangler=newRectangle(5,4);\x05\x05

packagecom.test;publicclassComplexNum{\x05//Z=a+bi\x05privateintRez;\x05//实部\x05privateintImz;\x05//

2种差不多的方法,自己在VC6.0上面试试#include<iostream>usingnamespacestd;#definepi3.14classcircle{public:circl
