Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1

Answer 1

we'll need more information but i'm guessing you are trying to access a memory past the size of your array?



it usually occurs when you create, say, an array of 5 (int[5] sample_array;) and tried to access the 6th one (sample_array[6] will cause an array out of bounds exception).



Also take note that an int[5] will allow you to store 5 items from indices 0 to 4, so sample_array[5] will also cause an out of bounds exception.

Answer 2
