No matter what is the detail, the message means that you try to do something in a part of an array/list that does not exist.
One can suspect that the usage of same index for 2 parts of the code is the problem

Java

departmanlar[i].personeller[i] = new Personel(departmanlar[i].getdepNo());
             ^              ^

The only way to know the detail is to use the debugger to inspect the variables at error.

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

You should find pretty quickly what is wrong.

The debugger is here to only show you what your code is doing and your task is to compare with what it should do.

You are using the wrong indexer for the personeller array. It should be using ps, the number of personeller entries, not i which is the number of departmanlar entries.

Java

departmanlar[i].createPerList(ps); // ps is the count of personnel entries for this department

while (ps != 0) {
    departmanlar[i].personeller[i] = new Personel(departmanlar[i].getdepNo()); // using the wrong index value for personneller
    System.out.print("Personel ADI >> ");
    String pa = sc.next();
    departmanlar[i].personeller[i].setperAd(pa);  // still using the wrong index value for personneller
