Here is the program to subtract two given matrix of size NxN. we see here that how subtraction performed .so have a look here from given example.
import
java.util.Scanner;
public class SubtractTwoMatrix {
public static void
main(String[] args) {
Scanner scanner
= new Scanner(System.in);
System.out.print("Enter the Number of rows: ");
int rows
= scanner.nextInt();
System.out.print("Enter the Number of columns: ");
int columns
= scanner.nextInt();
int[][]
matrix1 = new int[rows][columns];
int[][]
matrix2 = new int[rows][columns];
System.out.println("Enter the Elements of First matrix");
for
(int i = 0; i < rows; i++) {
String num[]
= new Scanner(System.in).nextLine().split(" ");
for
(int j = 0; j < columns; j++) {
matrix1[i][j]
= Integer.parseInt(num[j]);
; // elements of first matrix.
}
}
System.out.println("Enter the Element of Second Matrix");
for
(int i = 0; i < rows; i++) {
String num[]
= new Scanner(System.in).nextLine().split(" ");
for
(int j = 0; j < columns; j++) {
matrix2[i][j]
= Integer.parseInt(num[j]);
; // elements of Second matrix.
}
}
int[][]
matrix3 = new int[rows][columns];
for
(int i = 0; i < rows; i++) {
for
(int j = 0; j < columns; j++) {
matrix3[i][j]
= matrix1[i][j] - matrix2[i][j];
}
}
System.out.println("The Subtraction of Two Matrices is");
for
(int i = 0; i < rows; i++) {
for
(int j = 0; j < columns; j++) {
System.out.print(matrix3[i][j]
+ " ");
}
System.out.println();
}
}
}
Output:
