hi i am sitting on a small library book exchange program in Java i want to understand programming a little more so my question is
i have this now
(buchRegal[0] == "" && buchregal_id[0] == null)
buchRegal[0] is a position from a String array and buchregal_id is part of a int Array. With this code i learned i can check if a place at array[0] is empty, now the problem i want it to check if there is something in it AND if so i want it to move to the next part of the array which should be array[0] and place it there until the end is reached
my english is bad by the way greetings
