Manipulate Complex Numbers

The following demonstrates how to manipulate complex numbers:

class Complex
{
        double real;
        double imag;
        Complex()
        {
        }
        Complex(double real,double imag)
        {
            this.real=real;
            this.imag=imag;
        }
        void addComplexNos(Complex comp1,Complex comp2)
        {
               this.real=comp1.real+comp2.real;
               this.imag=comp1.imag+comp2.imag;
        }
        void subtractComplexNos(Complex comp1,Complex comp2)
        {
               this.real=comp1.real-comp2.real;
               this.imag=comp1.imag-comp2.imag;
        }
        void multiplyComplexNos(Complex comp1,Complex comp2)
        {
              this.real=(comp1.real*comp2.real)-(comp1.imag*comp2.imag);
              this.imag=(comp1.real*comp2.imag)+(comp2.real*comp1.imag);
        }
        void divideComplexNos(Complex comp1,Complex comp2)
        {
               this.real=comp1.real/comp2.real;
               this.imag=comp1.imag/comp2.imag;
        }
        void displayNos()
        {
        System.out.println(real +"+"+imag+"i");
        }
}
public class ComplexOpr
{
public static void main(String args[])
{
         Complex cno1=new Complex(2,2);
         Complex cno2=new Complex(3,4);
         Complex result=new Complex();

         System.out.print("First Complex No            = ");
         cno1.displayNos();

         System.out.print("Second Complex No           =");
         cno2.displayNos();

         result.addComplexNos(cno1,cno2);
         System.out.print("Addition of Complex Nos     = ");
         result.displayNos();

         result.subtractComplexNos(cno1,cno2);
         System.out.print("Subtraction of Complex Nos  = ");
         result.displayNos();

         result.multiplyComplexNos(cno1,cno2);
         System.out.print("Product of Complex Nos      = ");
         result.displayNos();

         result.divideComplexNos(cno1,cno2);
         System.out.print("Division of Complex Nos     = ");
         result.displayNos();
      }
}
