what is main difference between array ana arraylist.

[Bosun Bello]

It's easier to just check out the API. I know arrays contains various methods for manipulating arrays. ArrayList on the other hand is just like a vector, but probably has a few more methods.

Pawan,
Welcome to Javaranch.
This is not an apt forum for your question. You can post similar questions in Java in General forums. Anyhow the following differences some to my mind immediately

Array
Can contain primitive types and Objects
Non Resizable
Supported at the java language level
all contained components of same type
ArrayList
Can only Contain Objects
Resizable-array implementation
Part of Collecions framework thus you have to import java.util to use it
all contained components may be of same type or different types.
