Answer 1

要改动两个地方：1.     public Number(int A_initRealPart,int A_initImagPart,int B_initRealPart,int B_initImagPart) 
    { 
     A_RealPart = A_initRealPart;  // "="左右两边的变量名写颠倒了
     A_ImagPart = A_initImagPart; 
     B_RealPart = B_initRealPart; 
     B_ImagPart = B_initImagPart; 
    } 
2. public class NumberMain 
{ 
    public static void main(String[] args) { 
        // TODO code application logic here 
        Number No1=new Number(); 
        No1.setA_ImagPart(10); 
        No1.setA_RealPart(20); 
        No1.setB_ImagPart(30); 
        No1.setB_RealPart(40); 
        // 下面几句是新增加的，都没有进行运算，当然输出全部是0了
        No1.acc_ComplexNumber_ImagPart();
        No1.acc_ComplexNumber_RealPart();
        No1.add_ComplexNumber_ImagNumber();
        No1.add_ComplexNumber_RealNumber();
        No1.mod_ComplexNumber_A();
        No1.mod_ComplexNumber_B();
        No1.sub_ComplexNumber_ImagPart();
        No1.sub_ComplexNumber_RealPart();
        // 以上几句是新增的        No1.printComplexNumber(); 
    } 
}

代码比较混乱，引用代码用java代码格式贴出来，别人也容易看。
你这个应该是那些计算的方法都没被调用吧
粗看一下，就是传了几个数进去，然后调用了一个toString方法打印了this.add_RealPart之类的值。
处理变量的方法从头到尾都没调用，那变量打印出来就是初始值0。
