In the video, we are told that arrays are objects and thus their default value is NULL. This statement is contradictory for 1D arrays as there arrays are objects but they hold 0 as default value.
2D arrays : "Arrays are objects"
Hi Aanchal,
When you just declare an integer array i.e.
int[] arr;
in the above statement arr is an integer array and compiler will assign a null value to it.
But when you intialize it with new keyword i.e.
int[] arr = new int[length];
the compiler will assign a continuous block of memory of size equal to lenght*4 bytes as one integer takes 4 bytes and in this every 4 byte block will store 0 by default.
