用c#编写一个复数类ComplexNumber并测试其功能,要求能进行复数间的基本数学运算:+

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace fushu{ class Complex { public double RealPart;//代表复数的实数部分 public double ImaginPart;//代表复数的虚数部分 public Complex()//构造函数，将复数的实部和虚部都置0。 { this.RealPart = 0; this.ImaginPart = 0; } public Complex(double r, double i)// 构造函数，形参 r 为实部的初值，i为虚部的初值。 { this.RealPart = r; this.ImaginPart = i; } public double getReal()//获得复数对象的实部； { return RealPart; } public double getImagin()//获得复数对象的虚部； { return ImaginPart; } //将当前复数对象与形参复数对象相加，所得的结果仍是一个复数值，返回给此方法的调用者。 public Complex complexAdd(Complex a) { a.RealPart = a.RealPart + this.RealPart; a.ImaginPart = a.RealPart + this.ImaginPart; return a; } // 将当前复数对象与形参复数对象相减，所得的结果仍是一个复数值，返回给此方法的调用者。 public Complex complexSub(Complex a) { Complex temp = new Complex(); a.RealPart = a.RealPart - temp.RealPart; a.ImaginPart = a.RealPart -temp.ImaginPart; return temp; } // 将当前复数对象与形参复数对象相乘，所得的结果仍是一个复数值，返回给此方法的调用者。 public Complex complexMulti(Complex a) { Complex temp = new Complex(); a.RealPart = a.RealPart * temp.RealPart; a.ImaginPart = a.RealPart * temp.ImaginPart; return a; } public static Complex operator +(Complex a, Complex b)//重载+ { return new Complex(a.RealPart + b.RealPart, a.ImaginPart + b.ImaginPart); } public static Complex operator -(Complex a, Complex b)//重载- { return new Complex(a.RealPart - b.RealPart, a.ImaginPart - b.ImaginPart); } public static Complex operator *(Complex a, Complex b)//重载* { return new Complex(a.RealPart * b.RealPart, a.ImaginPart * b.ImaginPart); } public void input() { Console.WriteLine("请输入复数的实数部分！"); this.RealPart = double .Parse (Console.ReadLine()); Console.WriteLine("请输入复数的虚数部分！"); this.ImaginPart = double.Parse(Console.ReadLine()); Console.WriteLine("您输入的复数是：{0}",this.ToString ()); } public override string ToString() { return RealPart +"+"+ImaginPart +"i"; } } class Program { static void Main(string args) { Complex complex1 = new Complex(1, 2); Complex complex2 = new Complex(3, 4); Console .WriteLine ("({0},{1})",complex1 .getReal(),complex1 .getImagin () ); Console.WriteLine("({0},{1})", complex2.getReal(), complex2.getImagin()); Console.WriteLine(complex1 .ToString ()); Console.WriteLine(complex2.ToString()); Complex temp = new Complex(); Console.WriteLine(temp.ToString()); temp = complex1 + complex2; Console.WriteLine("({0})+({1})={2}", complex1.ToString(), complex2.ToString(), temp.ToString()); temp = complex1 - complex2; Console.WriteLine("({0})-({1})={2}", complex1.ToString(), complex2.ToString(), temp.ToString()); temp = complex1 * complex2; Console.WriteLine("({0})*({1})={2}", complex1.ToString(), complex2.ToString(), temp.ToString()); Complex c1 = new Complex(); Complex c2 = new Complex(); Complex c3 = new Complex(); c1.input(); c2.input(); c3 = c1 + c2; Console.WriteLine("({0})+({1})={2}", c1.ToString(), c2.ToString(), c3.ToString ()); c3 = c1 - c2; Console.WriteLine("({0})-({1})={2}", c1.ToString(), c2.ToString(), c3.ToString()); c3 = c1 * c2; Console.WriteLine("({0})*({1})={2}", c1.ToString(), c2.ToString(), c3.ToString()); Console.ReadKey(); } }}你面功能很全，按你需要的用

java中根据要求编程实现复数类ComplexNumber.

public class ComplexNumber{ComplexNumber(double r,double i){RealPart=r;maginaryPart=i;}double getRealPart() { return RealPart;}double getImaginaryPart(){return maginaryPart;}double complexAdd(ComplexNumber c) {sum=maginaryPart+RealPart;return sum;}public static void main(String args){ComplexNumber cn=new ComplexNumber(4,7);System.out println("复数"+cn+"的实部与虚部之和为："+)}private double RealPart,maginaryPart,sum;}

求大神帮忙 用java写复数类ComplexNumber

引用apache里的数学包，maven引用-------------------------------------------------------《dependency》《groupId》org.apache.commons《/groupId》《artifactId》commons-math3《/artifactId》《version》3.2《/version》《/dependency》-------------------------------------------------------包里有Complex复数类，各类操作都有我们的口号是：不重复发明轮子^_^

java面向对象程序设计 5.创建一个复数类ComplexNumber，以进行复数相加运算复数具有如下格式：

public class FuShu{ public int ShiBu; public int Xubu; public static FuShu operator +(FuShu src, FuShu des) { FuShu ret=new FuShu(); ret.ShiBu=src.ShiBu+des.ShiBu; ret.Xubu=src.Xubu+des.Xubu; return ret; } public override string ToString() { return "The Value is: " + this.ShiBu + "+" + this.Xubu+"!"; }} FuShu des = new FuShu(); des.ShiBu = 4; des.Xubu = 3; FuShu src = new FuShu(); src.Xubu = 66; src.ShiBu = 7; FuShu ret = src + des; MessageBox.Show(ret.ToString());转来的，问题属于操作符重载问题

复数(complex number) 判断

实数和虚数合称复数，简单说中学阶段所遇到的都是复数。方程x^2-2x+6=0的判别式小于0，它没有实数根，所以它的根是虚数，当然也是复数。
