#JAVA ARRAY VS ARRAYLIST PERFORMANCE HOW TO#

References of the actual objects are stored at contiguous locations. Therefore in ArrayList, the actual objects are never stored at contiguous locations. Output Successfully compiled and executedīase 4: Since ArrayList can’t be created for primitive data types, members of ArrayList are always references to objects at different memory locations (See this for details).

ArrayList is a part of the collection framework and is present in java.util package. It can be shrunk or expanded based on size. Note: ArrayList in Java (equivalent to vector in C++) having dynamic size. Here Type is the type of elements in ArrayList to be created Syntax: Declaring an Arraylist Arraylist al = new ArrayList Now let us dwell on the next concept of ArrayList that is as follows It is very important statement and is left unveiliable when it comes to deep understanding of memory storage in arrays. Note: arr(0) returns the first element of the array so it does mean that if we try to print out arr(0) then we will get Element1. which is containing continuous 100 block associated in it This does means we are declaring a memory block named 'arr' It is preferable if we have very limited array elements

Type 1: Declaring and initializing at the same time.
