Question

I have the following matrix

 1 2 3 4 5 6
 2 3 4 5 6 1
 3 4 5 6 1 2
 4 5 6 1 2 3
 5 6 1 2 3 4
 6 1 2 3 4 5

…and I want to have it in a table

 | 1 2 3 4 5 6
---------------
1| 1 2 3 4 5 6
2| 2 3 4 5 6 1
3| 3 4 5 6 1 2
4| 4 5 6 1 2 3
5| 5 6 1 2 3 4
6| 6 1 2 3 4 5

Having n elements is it possible to print such a table dynamically?

    public static void main ( String [ ] args ) {
        int n = Integer.parseInt(args[0]);
        for(int w = 1; w <= n; w++){
            System.out.println("");
            for(int p = w; p <= n + w - 1; p++){
                System.out.print((p-1)%n+1 + " ");
            }           
        }
    }

Depends on the array, assuming that you know the array size beforehand sure. In Java arrays can be jigged aka subarrays do not have to be same size, what in mind:

For test case:

public static void main(String[] args) {
    System.out.println(toTableString(new int[][] { { 1, 2, 3, 4, 5, 6 },
            { 2, 3, 4, 5, 6, 1 }, { 3, 4, 5, 6, 1, 2 },
            { 4, 5, 6, 1, 2, 3 }, { 5, 6, 1, 2, 3, 4 },
            { 6, 1, 2, 3, 4, 5 } }));
    System.out.println();
    System.out.println(toTableString(new int[][] { { 1 }, { 2, 3 },
            { 3, 4, 5 }, { 4, 5, 6, 1 }, { 5, 6, 1, 2, 3 },
            { 6, 1, 2, 3, 4, 5 } }));
    System.out.println();
    System.out.println(toTableString(new int[][] { { 1 }, { 20, 300 },
            { 3000, 40000, 50000 }}));
}

Output:

 | 0 1 2 3 4 5 
——————————————
0| 1 2 3 4 5 6 
1| 2 3 4 5 6 1 
2| 3 4 5 6 1 2 
3| 4 5 6 1 2 3 
4| 5 6 1 2 3 4 
5| 6 1 2 3 4 5 

 | 0 1 2 3 4 5 
——————————————
0| 1 
1| 2 3 
2| 3 4 5 
3| 4 5 6 1 
4| 5 6 1 2 3 
5| 6 1 2 3 4 5 

     | 00000 00001 00002 
————————————————————————
00000| 00001 
00001| 00020 00300 
00002| 03000 40000 50000
