Array declaration

[roshni bhagat]

Is this declaration correct:
int[] arr = new int[5][];

[Rob Spoor]

No it isn't.

The declared type is int[] - array of integers.
The initialized type is int[][] - array of array of integers.

So either add a [] in the declaration, or remove the [] (keep the [5]) in the initialization.

[Paul Sturrock]

No. Doesn't your compiler tell you this?

int[] arr =

creates a variable which references a one dimensional array of primitive integers.

 new int[5][];

creates a two dimensional array of primitive integers.

You can't assign one to the other.
