Add Two Complex Numbers and Display Sum in Java

a+bi is the common form of a complex number. Here number part ‘a’ is known as ‘real part’ and b is known as imaginary part. If a+bi and c+di are two complex numbers, then its sum is (a+c) + (b+d)i. 

This is a java console program to add any two complex numbers by user. 
Here class name is ‘complex’, so you should save your file with name ‘complex.java’.

Program Code:

import java.io.*;
class complex
{
  int real1,imag1,real2,imag2;

 void get() throws IOException
  {
      BufferedReader Br = new BufferedReader(new InputStreamReader(System.in));
     System.out.print("\n Enter the real part of first complex number: ");
     real1=Integer.parseInt(Br.readLine());
  System.out.print(" Enter the imaginary part of first complex number: ");
     imag1=Integer.parseInt(Br.readLine());
  System.out.print("\n Enter the real part of second complex number: ");
     real2=Integer.parseInt(Br.readLine());
  System.out.print(" Enter the imaginary part of second complex number :  ");
     imag2=Integer.parseInt(Br.readLine());
  }
void display()
  {   
      System.out.println(" \n Sum of complex numbers " + real1 + "+" + imag1 + "i and "  + real2 + "+" + imag2 + "i is " + (real1+real2) + "+" + (imag1+imag2) + "i");
  }

public static void main(String p[]) throws IOException
 {
   complex cmp = new complex();
   cmp.get();
   cmp.display();
 }
}

Sample output: 

Enter the real part of first complex number : 2
Enter the imaginary part of first complex number : 3 

Enter the real part of second complex number : 5
Enter the imaginary part of second complex number : 7 

Sum of complex numbers 2+3i and 5+7i is 7+10i
