Matrix in Java

We can implement a matrix using two dimensional array in Java. The element at row “r” and column “c” can be accessed using index “array[r]“.

Matrix Programs in Java

Since we are using two-dimensional arrays to create a matrix, we can easily perform various operations on its elements. In this tutorial, we will learn how to create a matrix from user input. Then we will add, subtract, and multiply two matrices and print the result matrix on the console.

1. Adding Two Matrix

Here is the simple program to populate two matrices from the user input. Then add its elements at the corresponding indices to get the addition of the matrices. Finally, we will print the sum of the matrices.

2. Subtracting Two Matrices

Here is the function to subtraction second matrix elements from the first matrix and then print the result matrix.

3. Multiplying Two Matrices

Below method will multiply the matrix elements and print the result matrix.
