More String Manipulation

1. Write a Java method isPalindrome() that receives a String and returns true if the string is a palindrome.
   
   
   
2. Write a Java method that receives a string parameter. Return a string where for every char in the original, there are three chars.
   Sample Output:
   tripleChar("AB") returns: "AAABBB"
   tripleChar("hello") returns: "hhheeellllllooo"
   
   
   
3. Write a Java method that receives a string parameter and an int n. Return a string made of n repetitions of the last n characters of the string. You may assume that n is between 0 and the length of the string, inclusive.
   Sample Output:
   repeatEnd("Hello", 3) returns: "llollollo"
   repeatEnd("Hello", 2) returns: "lolo"
   repeatEnd("Hello", 1) returns: "o"
   
   
   
   
4. Write a Java method that receives a string parameter. Return the number of words ending in 'e' or 'a' (not case sensitive). (Note: Character.isLetter(char) tests if a char is an alphabetic letter.)
   Sample Output:
   countAE("Every day is a fine and beautiful day.") returns: 2
   countAE("I love a banana with my cornflakes.") returns: 3
   
   
   
   
5. Write a Java method that receives a string parameter. Return the length of the largest "block" in the string. A block is a run of adjacent chars that are the same.
   Sample Output:
   maxBlock("hoopla") returns: 2
   maxBlock("abbCCCddBBBxx") returns: 3
   maxBlock("") returns: 0
