Two dimensional array

Question

int[ ][ ] myArr = { {1, 2, 3}, {4}, {5, 6, 7} };

Does this array creates a table like below
1 2 3
4
5 6 7

Can anyone explain why is this called Two dimensional array ? is this just because we have got 2 sets of square brackets while declaring an array?

Answer 1

You can print your array with
System.out.println(Arrays.deepToString(myArr));
if you're confused, see:

In Java a 2d array is an array inside an array, that explains the brackets ^.^
In each bracket pair inside the first array you define the rows and the columns result from that definition. Always helps me to see a 2d array as a table, so I don't get confused to access the values...
