infinite array ?

[9anth3r]

Not sure "infinite array" would be the right term but,

Is there away to define an array of unspecified size ?

Say if i need to store a bunch of int's in an array, but i and the user thats going to enter them doesn't know how many there is going to be. I guess i just don't wanna waste the memory by using a big partially filled array.

Please ignore my ignorance, im still very new to java.

An array is by definition of specified size, because at declaration time, memory is reserved. If you want one that grows or shrinks in size as and when you need, look at the class java.util.Vector or java.util.ArrayList.

(The only diff really being that Vector is synchronized, and ArrayList is not. Use ArrayList unless many different threads are modifying the contents of your array simultaneously).

by using ArrayList, you can use trimSize() method to trim down your ArrayList - after you fill in the array with int's
data.
