Expert Solution & Answer
Chapter 15.1, Problem 15.4CP
Explanation of Solution
Event-driven:
When a GUI (Graphical User Interface)
Example:
Consider a program that calculates the sum of two numbers, the user can enter two numbers in the “GUI” designed.
- The user can enter the number that needs to be added.
- The sum will be calculated only when the user click on the calculate button...

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
