1. Create a Person.java file. Implement the public Person and Student classes in Person.java, including all the variables and methods in
the UMLS.
Person
-name: String
-street: String
-city: String
+Person(String name, String, street, String, city)
+getName(): String
+setName(String name): void
+getStreet(): String
+setStreet(String street): void
+getCity(): String
+setCity(String City): void
+toString(): String
Student
-Id: int
+Person(String name, String, street, String, city, int Id)
+getId(): int
+setId(int Id): void
+toString(): String
2. Create a StudentTest.java file. Implement a public StudentTest class with a main method. In the main method, create one student
object and print the object using System.out.println().
Your printing result must follow the example output:
name: Mike, street: Morris Ave, city: Union, Id: 1000
Hint: You need to modify the toString methods in the Student class and Person class!

Show the status of the Finite Automata at the conclusion of the Paint Blue Algorithm (mark the
visited states with an X and only include edges that have not been followed).
2) Use the pumping lemma to prove the following language is nonregular:
L= {ab} = {abbb, aabbbbbb, aaabbbbbbbbb, ...}
3) Find CFGs that for these regular languages over the alphabet Σ= {a, b}. Draw a Finite Automata
e CFG.

For example if the user inputs the value 243 the program will output 9 because 2 + 4 + 3 = 9.

Then to choose a random number from 1 to 100 and the computer program will attempt to guess it, displaying the directions calculated or not. The guess will be displayed and the user will answer if it was correct or not. If correct, the game ends, if not then the computer asks if the guess was too high or too low. Finally inputting an answer and the computer generates a new guess within the proper range. Oh and to make sure the program doesnt guess outside of the ranges produced by the inputs of “too high” and “too low”.
