If we want to arrange a collection of objects into an other object then we will use either ArrayList or Vector. When we use these classes all the objects that are placed in it will be stored sequentially one after the other.

ArrayList : If we want to store same type of objects then we will use ArrayList class.

Vector : If we want to store different type of objects then we will use Vector class.
