Class Menu - Palin - Count - ICSE - PROJECT: Import Class Char Int Void

This document contains the code for a Java program that analyzes strings for palindromes and counts vowels. It defines a Menu_Palin_Count class with Palin() and count() methods to check for palindromes and count vowels respectively. The main() method gets user input, calls the appropriate method based on the choice, and passes the string for analysis.
