Java two dimensional array example

import java.util.Scanner;

public class TwoDiementionalArrayExample{ 
    public static void main(String... z)
    {
       int a[][];
       int n;
        Scanner uk = new Scanner(System.in);
        System.out.println("Enter the number of element");
         n = uk.nextInt();
         a = new int[n][n];

    for(int i = 0; i < a.length; i++){
        for(int j = 0; j < a[i].length; j++){
           a[i][j]=uk.nextInt();
        }
    }
    	System.out.println("Output:");
        for(int i = 0; i < a.length; i++){
        for(int j = 0; j < a[i].length; j++){
            System.out.print(a[i][j]+"\t");
        }
        System.out.println("\t");
}
    }
}

Enter the number of element
3
1 2 3
4 5 6
7 8 9 
Output:
1	2	3		
4	5	6		
7	8	9
