Subtraction of Two Matrix in Java program

import java.util.*;
class subtractmatrix
{
  public static void main(String args[])
  {
    Scanner sc = new Scanner(System.in);
    int i,j,n;
    System.out.print("Enter a order of matrix=");
    n=sc.nextInt();
    int a[][]=new int[n][n];
    int b[][]=new int[n][n];
    int c[][]=new int[n][n];
    System.out.println("Enter a first matrix in A:\n");
    for(i=0;i<n;i++)

      for(j=0;j<n;j++)
      {
        a[i][j]=sc.nextInt();
      }
    }
    System.out.println("Enter a second matrix in B:\n");
    for(i=0;i<n;i++)

    System.out.println("Subtraction of A and B:");
    for(i=0;i<n;i++)
    {
      for(j=0;j<n;j++)
      {
        System.out.println(c[i][j]=a[i][j]-b[i][j]);
      }
    }
  }
}

Output:

Enter a order of matrix=2
Enter a first matrix in A:
7 8
5 6
Enter a second matrix in B:
1 2
3 4
Subtraction of A and B:
6
