So, i'm using an array in my program, and it gives me this error:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

The error is in fourth line of this code: 

int n = numbers.length, numBigger10 = 0; 
for (int i = 0; i < n; i++)
            if (numbers[i] > 10)
                numbersBigger10[i] = numbers[i];               
                numBigger10++;

What can I do to solve?

If you want to know more details about the error please feel free to ask.

The reason you are getting this NullPointerException is because in your if statement you are trying to assign numbers[i] to an index location that is not present in the numbersBigger10 array.

i.e. The two arrays, numbers and numbersBigger10 have different sizes.

edit - It would be helpful to see more code though, specifically the part where you declared numbersBigger10.
