int dif = apples.get[i]+m;

I’m not a Java guy, but if apples is just an array of integers, do you need a getter? Can’t it just be:

int dif = apples[i]+m;

Also, do we know that a the length of the array? Or at least <=?

If that doesn’t work, try logging out the variables so you can see what is happening.

@tridib98

int dif = apples.get[i]+m;

Thanks Kevin but the issue was in just in brackets.
The line should follow this → int dif = apples.get(i)+m; instead of int dif = apples.get[i]+m;

Looks like this is an ArrayList which apparently needs a getter. This probably would have been nice information to have
