Double的Complex()的方法

class Complex{

   //instance variables
   double real,imag;


   public static void main(String args[]){
      Complex a=new Complex(1.0,1.1);
      Complex b=new Complex(1.0,1.1);
      boolean c=a.equals(b);
      System.out.println(c);
   }


   //constructor
   public Complex(){
      this.real=0.0;this.imag=0.0;
   }

   //constructor
   public Complex(double real,double imag){
      this.real=real;this.imag=imag;
   }

   public boolean equals(Complex b){
      if(b==null) return false;
      return (real==b.real && imag==b.imag);
   }
}
