Oversized array vs arraylist how to#

This does means we are declaring a memory block named 'arr' It is preferable if we have very limited array elements

Type 2: Declaring than initializing elements later.

Type 1: Declaring and initializing at the same time.

Dynamically sized arrays int arr = new int.

In Java, the following are two different ways to create an array. Note: As a side note, ArrayList in Java can be seen as similar to vector in C++. Now moving ahead even with ArrayList there comes a functionality to pass the type of datatype of elements that are supposed to be stored in the ArrayList be it an object, string, integer, double, float, etc. Being a good programmer one is already aware of using ArrayList over arrays despite knowing the differences between these two. As we all are aware of that arrays are linear data structures providing functionality to add elements in a continuous manner in memory address space whereas ArrayList is a class belonging to the Collection framework. Let us discuss the concept of the arrays and ArrayList briefly in the header to incorporate the understanding in java programs later landing onto the conclusive differences between them.
