我把方法給你寫出來，測試程序的主函數(shù)你就自己寫把

/**

//編寫一個類ComplexNumber實現(xiàn)復(fù)數(shù)的運算:

public class ComplexNumber {

double m_dRealPart;

double m_dImaginPart;

public ComplexNumber(double r,double i){

this.m_dRealPart = r;

this.m_dImaginPart = i;

}

public double getRealPart(){

return m_dRealPart;

}

public double getImaginPart(){

return m_dImaginPart;

}

public void setRealPart(double d){

m_dRealPart = d;

}

public void setImaginaryPart(double d){

m_dImaginPart = d;

}

public ComplexNumber compexAdd(ComplexNumber c){

ComplexNumber x = new ComplexNumber(getRealPart(),getImaginPart());

x.m_dImaginPart = c.m_dImaginPart + m_dImaginPart;

x.m_dRealPart = c.m_dRealPart + m_dRealPart;

return x;

}

public ComplexNumber complexMinus(ComplexNumber c){

ComplexNumber x = new ComplexNumber(getRealPart(),getImaginPart());

x.m_dImaginPart = c.m_dImaginPart - m_dImaginPart;

x.m_dRealPart = c.m_dRealPart - m_dRealPart;

return x;

}

public ComplexNumber complexMulti(ComplexNumber c){

ComplexNumber x = new ComplexNumber(getRealPart(),getImaginPart());

x.m_dImaginPart = c.m_dImaginPart * m_dImaginPart;

x.m_dRealPart = c.m_dRealPart * m_dRealPart;

return x;

}

public String toString(){

return m_dRealPart +"+"+ m_dImaginPart +"i";

}

}

總結(jié)

以上是生活随笔為你收集整理的java代码复数包括虚部和实部,Java中编写Applet程序验证复数类(在问题补充中)实现接收用户输入的复数的实部和虚部,计算复数与复数,复数与实数的加减,乘除操作...的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
