Remove Items From ArrayList in Java

Another way to change the data in an ArrayList is with the .remove() method.

.remove() takes one parameter which represents an index and removes the element placed at that index:

List<Integer> threeArr = new ArrayList<>(List.of(1, 4, 6));

// Remove second element:
threeArr.remove(1);

// threeArray has now the value {1, 6}

// Remove first element:
threeArr.remove(0);

// threeArray has now the value {6}
