Building a Utility class with static Methods

In this problem, you will create a program that implements three static methods in a StringUtil class (character counting, string reversal, and palindrome checking), processes a string read from Scanner, and displays the results to standard output.

Learning Objective: Understand designing utility classes with combined static methods

Overview

Define static methods in a StringUtil class to process strings.

Specifications

1. StringUtil.countChar(String s, char c): Returns the count of character c in string s
2. StringUtil.reverse(String s): Returns the reversed string
3. StringUtil.isPalindrome(String s): Returns true if string is a palindrome
4. Read one line from Scanner
5. Print count of 'a', reversed string, and palindrome check

Input Example

racecar

Output Format

Count of 'a': 2
Reversed: racecar
Palindrome: true
