We are going to share a Java Program to Perform Complex Number Multiplication. If you are a Java beginner and want to start learning the Java programming, then keep your close attention in this tutorial as I am going to share how to write a Java Program to Perform Complex Number Multiplication.
Copy the below Java program and execute it with the help of Javac compiler. At the end of this program, We have shared the output of this program.

Enter the dimension of the square matrix:
2
Enter the complex elements of matrix:
1 2 1 2
1 2 1 2
Enter the complex elements of matrix:
1 2 1 2
1 2 1 2
The Multiplication is:
-6.0+8.0i -6.0+8.0i
-6.0+8.0i -6.0+8.0i
