### Write a Java program to calculate the Multiplication of two matrix.

Read two matrix as two 2D array. Now multiply the array elements as matrix.

```
import java.util.*;

class MatrixMultiply
{
public static void main()
{
int arr1[3][3],arr2[3][3],arr3[3][3],i,j,k;
Scanner sc=new Scanner(System.in);
System.out.println("Enter The 1st Matrix Elements\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
arr1[i][j]=sc.nextInt();
}
}
System.out.println("Enter The 2nd Matrix Elements\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
arr2[i][j]=sc.nextInt();
}
}

for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
arr3[i][j]=0;
for(k=0;k<3;k++)
{
arr3[i][j] += arr1[i][k] * arr2[k][j];
}
}
}

System.out.println("\nFinal array Elements\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
System.out.print(arr3[i][j] + "  ");
}
System.out.println("");
}
}
}
```
