Two dimensional array with different lengths (Java)

Question

Is there an opportunity to create two dimensional Arrays with different lengths in the second dimension? For example like this:

[true] [true] [true]

[true]

Answer 1

Yes, arrays in a 2D array don't have the have same size. E.g.:

boolean[][] twoDimensionalArray = new boolean[3][];
twoDimensionalArray[0] = new boolean[]{true, true, true};
twoDimensionalArray[1] = new boolean[]{true};
twoDimensionalArray[2] = new boolean[]{true, true, true, true, true};
