Program to add and Subtract Complex Numbers using Class in Java
In this article, we will try to add and subtract these two Complex Numbers by creating a Class for Complex Number, in which:
- The complex numbers will be initialized with the help of constructor.
- The addition and subtraction will be performed with the help of function calling.
- The function will be called with the help of another class.
Example:
Input: a1 = 4, b1 = 8
a2 = 5, b2 = 7
Output:
Sum = 9 + i15
Difference = -1 + i
Explanation:
(4 + i8) + (5 + i7)
= (4 + 5) + i(8 + 7)
= 9 + i15
(4 + i8) - (5 + i7)
= (4 - 5) + i(8 - 7)
= -1 - i
Input: a1 = 9, b1 = 3
a2 = 6, b2 = 1
Output:
Sum = 15 + i4
Difference = 3 + 2i

Output:
Complex number: 3 + 2i Complex number: 9 + 5i Sum of Complex number: 12 + 7i Difference of Complex number: -6 + -3i
