Class IntList

  • All Implemented Interfaces:
    Cloneable
    public class IntList
extends Object
implements Cloneable
    A Array-List for integer objects. Ints can be added to the list and will be stored in an int-array.

    Using this list for storing ints is much faster than creating java.lang.Integer objects and storing them in an ArrayList.

    This list is not synchronized and does not implement the full List interface. In fact, this list can only be used to add new values or to clear the complete list.
