Hello,
i have 2D array and initialise it with nested loop. More specific in place array[11][2] initialise it as element of another class i created. Now if i use system.out to print this place after the end of loop, content is ok, but if i print it in a method i created is null!!! Im not doing anything in that place in that method, just system.out. Any idea???
thank you
EDIT: Noticed that in method all elements of the array are NULL.Why? when that happens?

Without seeing any code I can think of a few possible causes:
- scope
- assignment going wrong
- ..

it is impossible to say without seeing your code. Clearly you are doing something wrong, or not doing something right. So please post what you have (and only the relevant part please!!!).

If all the elements of your array or null it seems like your initializing the array incorrectly. Look through the Java array tutorial and see if that helps you figure it out.
