Ways To Print Metrix Program in JAVA ( Addition, Subtraction, Multiply) | Learn by Java2021

Write a program to print addition of two metrix

public class Addmetrix {
    public static void main(String[] args)
    {
        int a[][]={{3,4,2},{4,5,6},{7,8,9}};
        int b[][]={{3,4,2},{4,1,2},{7,8,9}};
        int add[][]=new int[3][3];
        for (int i=0;i<a.length;i++){
            for (int j=0;j<b.length;j++){
                add[i][j]=0;
                for (int k=0;k<add.length;k++){
                    add[i][j]=a[i][k]+b[k][j];
                }
                System.out.print(add[i][j]+" ");
            }
            System.out.println();
        }
    }
}
OUTPUT  : 

Write a program to print Multiplication of two metrix

public class Mulmetrix {

    public static void main(String[] args)

    {

        int a[][]={{3,4,2},{4,5,6},{7,8,9}};

        int b[][]={{3,4,2},{4,1,2},{7,8,9}};

        int add[][]=new int[3][3];

        for (int i=0;i<a.length;i++){

            for (int j=0;j<b.length;j++){

                add[i][j]=0;

                for (int k=0;k<add.length;k++){

                    add[i][j]=a[i][k]*b[k][j];

                }

                System.out.print(add[i][j]+" ");

            }

            System.out.println();

        }

    }

} 

OUTPUT : 

Write a program to print Subtraction of two metrix

public class Submetrix {

    public static void main(String[] args)

    {

        int a[][]={{3,4,2},{4,5,6},{7,8,9}};

        int b[][]={{3,4,2},{4,1,2},{7,8,9}};

        int add[][]=new int[3][3];

        for (int i=0;i<a.length;i++){

            for (int j=0;j<b.length;j++){

                add[i][j]=0;

                for (int k=0;k<add.length;k++){

                    add[i][j]=a[i][k]-b[k][j];

                }

                System.out.print(add[i][j]+" ");

            }

            System.out.println();

        }

    }

}
