This code shows three ways to create an array of integers.
Any book on Java will explain arrays. Try Thinking in Java by Bruce Eckel, available free at bruceeckel.com. You cannot change the size of an array. If you need to add elements to a "full" array, you must allocate a new array, then copy all elements from the old array to the new. The method System.arraycopy does this most efficiently. Instead of using an array, prefer use of a collection class (such as ArrayList, which implements the interface List), which handles all this for you. -Jeff-
