Design and implement a class that inputs a string and creates a copy of the input string with the characters in reverse order.
Design and implement a class that inputs a long string and counts the number of times that the word "and" appears; the class should display this number on the console.
Design and implement a class that inputs a string and checks if the string is a palindrome; if so, it displays the message "is a palindrome" on the console. A palindrome is a string that does not change when the characters are changed to reverse order.
Design and implement a class that inputs a string and checks if the string starts with the substring "Mr. " or with the string "Mrs. ". Note the space after the dot. If the input string does not include any one of these substrings, the class should display a message.
Design and implement the solution to a problem that sets up an array of objects of class Person. The solution should carry out a binary search of the name of the objects looking for a specific string value (the target string). Hint: modify class Marrayperson in Chapter 9.
Design and implement a solution to a problem that rearranges an array of objects of class Person. For this, use selection sort. Hint: modify class Marrayperson in Chapter 9.
