Chapter 8.2, Problem 8STQ

Give a complete definition of a class called Titiledperson, which you derive from the class Person in Listing 8.1. The class TitiedPerson has one additional String instance variable for a title, such as Ms., Mr., or The Honorable. The class TitiedPerson has two constructors: a default constructor and one that sets both the name and the title. It has a writeOutput method, a rest method, an equals method, an accessor method getTitle that returns the title, and a mutator method setTitle that changes the person’s title. For two titled people to be equal, they must have the same name and the same title. You may want to use the class Student, in Listing 8.2 is as a model.

Consider a class that could be used to play a game of hangman. The classhas the following attributes:- the secret word- the disguised word, in which each unknown letter is replaced with a question mark (?). For example, if the secret word isabracadabra and the letters a, b, and e have been guessed, the disguisedword would be ab?a?a?ab?a.- the number of guesses made- the number of incorrect guessesIt will have the following methods:- makeGuess(c) guesses that character c is in the word.- getDisguisedWord returns a string containing correctly guessed letters in their correct positions and unknown letters replaced with ?.- getSecretWord returns the secret word.- getGuessCount returns the number of guesses made.- isFound returns true if the hidden word has been discovered.a. write method heading for eeach methodb. write preconditions and postconditions for each methodc. write some java statements that test the classd.
