public class DynamicIntArray
extends java.lang.Object
implements java.io.Serializable
java.util.ArrayList, but specifically for
ints. This is basically an array of integers that resizes
itself (if necessary) when adding new elements.| Constructor and Description |
|---|
DynamicIntArray()
Constructs a new array object with an initial capacity of 10.
|
DynamicIntArray(int initialCapacity)
Constructs a new array object with a given initial capacity.
|
DynamicIntArray(int[] intArray)
Constructs a new array object from the given int array.
