public class Complextest{
public static void main(String []args){
complex c1,c2,c3;
String temp;
c1=new complex(3,4);
c2=new complex(2,3);
c3=new complex();
System.out.println("第1个复数的实数是"+c1.getReal()+"虚数是"+c1.getImagin());
System.out.println("第2个复数的实数是"+c2.getReal()+"虚数是"+c2.getImagin());
c3=c1.complexAdd(c2);
System.out.println("这两个复数相加得:");
c3.complexToString();
c3=c1.complexMinus(c2);
System.out.println("这两个复数相减得:");
c3.complexToString();
c3=c1.complexMulti(c2);
System.out.println("这两个复数相乘得:");
c3.complexToString();
}
}
特点是这段代码complex complexMulti(complex number){
complex result=new complex();
result.real=this.real*number.real-this.imagin*number.imagin;
result.imagin=this.real*number.imagin+this.imagin*number.real;
return result;
是怎样实现两个复数的相加的.?
