Working with Strings

In a class named MyStringUtilities, write the methods with the prototypes given below:

public static String reverse(String s)   This method accepts a String s and returns a new String with all the characters reversed.

public static boolean isPalindrome(String s) This method accepts a String s and returns true if  s is a palindrome, false otherwise.

public static String changeCase(String s) This method accepts a String s and returns a new String with all the characters changed in case. That is, lower case made upper case; and upper case made lower.

public static boolean isAnagram(String s1, String s2) This method accepts two Strings s1 and s2, and returns true if s1 and s2 are anagrams, false otherwise.

Use the main method in another class to prompt the user for Strings to test these methods.
