Name: ArrayList Date: 2025-07-23 Aim: Write a menu-driven Java program inside a class called ArrayListMenuProgram to perform basic operations— search , delete , display , and exit —on an ArrayList of integers.The menu needs to be displayed in this format. Menu: 1. Search for an element 2. Delete an element 3. Display elements 4. Exit Input Format : • The first line of input contains a single integer , which represents the number of elements to be added to the list. • The next lines each contain one integer — these are the elements to be inserted into the list. • After inserting the elements, the program enters a menu loop. • For each iteration of the menu: • A single integer is entered to represent the menu choice. • If the choice is (Search), the next line will contain an integer to search for in the list. • If the choice is (Delete), the next line will contain an integer to delete from the list. • If the choice is (Display), no additional input is expected. • If the choice is (Exit), the program ends. • The menu is repeated after each operation until the user selects • Invalid Option (Default Case): If the user inputs a number other than , , , or , it has to print as: " Invalid choice. Please enter a valid option ". Output Format : Based on the user's menu choice: • If is chosen: • The program expects a number to be entered. If found print, "< X > is found " If not found print, "< X > is not found " • If is chosen: • The program expects a number to be entered. If deleted print, "< X > is deleted " If not present print, "< X > does not exist " • If is chosen: • Print: " Current elements: [a, b, c, ...] " • If is chosen: • Print: " Exiting program " n n 1 2 3 4 4 1 2 3 4 1 2 3 4 ID: 111524104013 Page No: 2 R.M.D. Engineering College 2024-2028-ECE-A Note: • Refer to the sample test cases for a better understanding of the input and output formats.
