Matrix Manipulation Using Java

In this blog, you will learn about matrix addition, matrix subtraction, matrix multiplication.

Introduction

 

In this blog, I will explain about matrix manipulation in Java. It is very simple in Java Programming. The output will be displayed in the Run module.

  

Software Requirement

 

JDK1.3.

  

Matrix Manipulation

 

In this program, I explain about matrix addition, subtraction, and multiplication.

Simple program

class mat {
 public static void main(String arg[]) {
  int a[][] = {
   {
    1,
    2
   },
   {
    3,
    4
   }
  };
  int b[][] = {
   {
    1,
    2
   },
   {
    3,
    4
   }
  };
  int c[][] = new int[2][2];
  int i, j, k;
  System.out.println("\nGiven A Matrix is...");
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    System.out.print(a[i][j] + "\t");
   }
   System.out.println("\n");
  }
  System.out.println("\nGiven B Matrix is...");
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    System.out.print(b[i][j] + "\t");
   }
   System.out.println("\n");
  }
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    c[i][j] = a[i][j] + b[i][j];
   }
  }
  System.out.println("\nMatrix Addition is...");
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    System.out.print(c[i][j] + "\t");
   }
   System.out.println("\n");
  }
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    c[i][j] = a[i][j] - b[i][j];
   }
  }
  System.out.println("\nMatrix Subtraction is...");
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    System.out.print(c[i][j] + "\t");
   }
   System.out.println("\n");
  }
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    for (k = 0; k < 2; k++) {
     c[i][j] = c[i][j] + a[i][k] * b[k][j];
    }
   }
  }
  System.out.println("\nMatrix Multiplication is...");
  for (i = 0; i < 2; i++) {
   for (j = 0; j < 2; j++) {
    System.out.print(c[i][j] + "\t");
   }
   System.out.println("\n");
  }
 }
}
