java虚数的加减乘除运算的程序怎么编啊

//Xushu.java

public class Xushu {

public static void main(String[] args) {

System.out.println(Data.add(new Data(5,3),new Data(8,3)))

}

}

class Data {

private double real// 表示实部

private double vir// 表示虚部

public Data(double real, double vir) {

this.real = real

this.vir = vir

}

static Data add(Data a,Data b) {

b.real += a.real// 实部相友败加

b.vir += a.vir// 虚部相加

return b

}

public String toString() {

return real+"+"+vir+"i"

}

}

//好知颤减乘除和这个类似,你根据他猛扮们的特性和逻辑在Data类里编写就可以了

public class Plus {

public static void main(String[] args) {

String fristParam = args[0]

String secondParam = args[1]

String result = plus(fristParam, secondParam)

System.out.println(result)

}

private static String plus(String _sFristParam, String _sSecondParam) {

String sResult = null

if (isVirtual(_sFristParam) || isVirtual(_sSecondParam)) {

sResult = virualPlus(_sFristParam, _sSecondParam)

}

else {

sResult = normalPlus(_sFristParam, _sSecondParam)

}

return sResult

}

private static String normalPlus(String _sFristParam, String _sSecondParam) {

if (_sFristParam == null || _sSecondParam == null) {

return "对不起输入有错，请重新输入"

}

int nFristParam = Integer.parseInt(_sFristParam)

int nSecondParam = Integer.parseInt(_sSecondParam)

int nResult = nFristParam + nSecondParam

String sResult = String.valueOf(nResult)

return sResult

}

private static String virualPlus(String _sFristParam, String _sSecondParam) {

String sFirstActual = getActual(_sFristParam)

String sFirstVirtual = getVirtual(_sFristParam)

String sSecondActual = getActual(_sSecondParam)

String sSecondVirtual = getVirtual(_sSecondParam)

String sResult = null

int nFirstActual = 0

int nFirstVirtual = 0

int nSecondActual = 0

int nSecondVirtual = 0

int nVirtual = 0

int nActual = 0

if (sFirstActual == null || sFirstVirtual == null || sSecondActual == null ||

sSecondVirtual == null) {

return "对不起输入的虚数有错，请重新输入"

}

nFirstActual = Integer.parseInt(sFirstActual)

nFirstVirtual = Integer.parseInt(sFirstVirtual)

nSecondActual = Integer.parseInt(sSecondActual)

nSecondVirtual = Integer.parseInt(sSecondVirtual)

nVirtual = nFirstVirtual + nSecondVirtual

nActual = nFirstActual + nSecondActual

String sVirtual = String.valueOf(nVirtual)

String sActual = String.valueOf(nActual)

sResult = sActual + "+" + sVirtual + "i"

return sResult

}

private static String getVirtual(String _sParam) {

String[] members = _sParam.split("\\+")

String sResult = (members[1] != null) ? members[1].substring(0, 1) : null

return sResult

}

private static String getActual(String _sParam) {

String[] members = _sParam.split("\\+")

String sResult = (members[0] != null) ? members[0] : null

return sResult

}

private static boolean isVirtual(String _sParam) {

return (_sParam.indexOf("i") != -1) ? true : false

}

}

自己改一下吧，基本上没问题

//===========================

结果演示:

您输入第一个复数是:5.0-5.0i

您输入第二个的复数是:9.0-4.0i

相加之后的结果是:14.0-9.0i

相乘之后的结果是：25.0-65.0
