And: in an array the values are side by side,
a collection will scatter the values to positions where they are most convenient.
Every collection has its pro's and con's.
E.g.: linked lists can insert an item quickly but are a drag to sort.

;JOOP!

An array is inherently fixed in size, whereas a Collection can grow. That's the most important difference

Arrays a basic structures. for example, an array of integers means every single insert in there is an integer.

while in collection, you don't have that limitation.

you can have first object being an integer, 2nd being a String, 3rd being a string, 4th being an INTEGGER..

noticed, string and INTEGGER are not typos, they are custom classes you can define.

SamsonChung, what would you say about this code piece?

     Object[] array = new Object[4];

     array[0] = "12345";
     array[1] = new Integer(6);
     array[2] = new Exception("Also!");
     array[3] = this;

???

;JOOP!
