JAVA Program to Perform Multiplication of Matrix

JAVA Program to Perform Multiplication of Matrix:

``` class Twodimult
{

public static void main(String args[])
{
int [][] A = {{1,2,3},{4,5,6},{7,8,9}};
int [][] B = {{1,2,3},{4,5,6},{7,8,9}};
int C[][] = new int[3][3] ;

int i,j,k;
System.out.println("Matrix A is \n");
for( i=0;i<3;i++)
{
for( j=0;j<3;j++)
{
System.out.print(" "+A[i][j]);
}
System.out.println();
}

System.out.println("\nMatrix B is \n");
for( i=0;i<3;i++)
{
for( j=0;j<3;j++)
{
System.out.print(" "+B[i][j]);
}
System.out.println();
}

// Multipication

for( i=0;i<3;i++)
{
for( j=0;j<3;j++)
{
for( k=0;k<3;k++)
{
C[i][j] = C[i][j]+(A[i][k])*(B[k][j]);
}
}
}

System.out.println("\nMultiplication is \n");
for( i=0;i<3;i++)
{
for( j=0;j<3;j++)
{
System.out.print(" "+C[i][j]);
//  System.out.format(" %5d", C[i][j]);
}
System.out.println();
}
}
}```

OUTPUT:

```Matrix A is

1 2 3
4 5 6
7 8 9

Matrix B is

1 2 3
4 5 6
7 8 9

Multiplication is

30  36  42
66  81  96
102 126 150```
