Removing an item from an array list
The problem is in this part: for (Student i : roster) { int sId = i.getId(); if (id == sId) { roster.remove(id); } else if (id != sId) { System.out.println("ERROR: Invalid student ID.\n"); } } You can't remove items from the list while you're looping through it with this for loop. If you want to use a loop, you should use this kind of loop: for (int i = 0; i < roster.size(); ++i) { Student s = roster.get(i); int sId = s.getId(); if (id == sId) { roster.remove(i); i--; // This is important! } } See, this lets you remove the student at the current index. However, as you remove it, you have to decrement the index, otherwise you'll skip the next item in the list. More on reddit.com

How to Delete Objects from ArrayList in Java? ArrayList.remove() method Example | Java67
That's all about how to take out an object from ArrayList in Java. Remember there are two methods to remove elements, first remove(int index) and second remove(Object obj), if you are working with ArrayList of Integer, Short, Byte, or Long then autoboxing may cause a problem for you, because a call to remove(1) may be interpreted as calls to remove(index) to remove a second element or a call to remove(Object) to remove the element with value 1.

list.subList(4, list.size()).clear();
Sublist operations are reflected in the original list, so this clears everything from index 4 inclusive to list.size() exclusive, a.k.a. everything after index 3. Range removal is specifically used as an example in the documentation:
This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list. For example, the following idiom removes a range of elements from a list:
list.subList(from, to).clear();

arrayList.add("3");
arrayList.add("4");

An ArrayList never shrinks. The size of an ArrayList does not always refer to the size of the underlying array. Instead it defines the number of accessible elements in that array. When removing an element that is not the last element in the list, the part of the array after the removed element will be shifted to fill the gap. After that the underlying array has one more slot with a null value at the end. The size of the ArrayList will be reduced by one. You can also look at the source code: public E remove(int index) { Objects.checkIndex(index, size); final Object[] es = elementData; @SuppressWarnings("unchecked") E oldValue = (E) es[index]; fastRemove(es, index); return oldValue; } private void fastRemove(Object[] es, int i) { modCount++; final int newSize; if ((newSize = size - 1) > i) System.arraycopy(es, i + 1, es, i, newSize - i); es[size = newSize] = null; }

A new array isn't created. The remaining elements are moved. One of the great things about open source is you can see for yourself how things are done.

In this specific case, you should remove the elements in descending order. First index 5, then 3, then 1. This will remove the elements from the list without undesirable side effects.
for (int j = i.length-1; j >= 0; j--) {
list.remove(i[j]);
}

You can remove elements from ArrayList using ListIterator,
ListIterator listIterator = List_Of_Array.listIterator();
/* Use void remove() method of ListIterator to remove an element from List.
It removes the last element returned by next or previous methods.
*/
listIterator.next();
//remove element returned by last next method
listIterator.remove();//remove element at 1st position
listIterator.next();
listIterator.next();
listIterator.remove();//remove element at 3rd position
listIterator.next();
listIterator.next();
listIterator.remove();//remove element at 5th position
