Program Plan Intro

“add” method in “ArrayList” class:

• • “add” method is used to add the particular element at the end of the list and increases the size of lists by one.
• • Users use the “add” method to set an element for the first time.

Example:

The example for adding string is given below:

Consider, “nameList” is an object of class “ArrayList<String>”. User can add the string “Rose” to the list “nameList” which is given below:

nameList.add("Rose");

User can also add the string for particular index on the given list. Suppose if user want to place a string at index “6” in the “nameList”. The index size starts from “0” to “7”.

nameList.add(6, "Merry");

The above code snippet is used to insert the name “Merry” at index “6”.
