Question
Chapter 3, Problem 4P
Program Plan Intro
a.
Decimal number system:
- In decimal system, the numbers from “0” to “9” are used.
- It means, in total, decimal system has 10 numbers.
- Therefore, the base used for decimal number system is 10.
Binary number system:
- In binary system, the numbers “0” and “1” are only used.
- It means, in total, binary system has only 2 numbers.
- Therefore, the base used for binary numbering system is 2.
Program Plan Intro
b.
Octal number system:
- Octal number system is also known as base-8 number system
- It is because; eight distinct elements from 0 to 7 are used to represent a level.
- It means, in total, octal system has 8 numbers.
Decimal number system:
- In decimal system, the numbers from “0” to “9” are used.
- It means, in total, decimal system has 10 numbers.
- Therefore, the base used for decimal number system is 10.
Program Plan Intro
c.
Hexadecimal number system:
- In hexadecimal number system, the numbers from “0” to “9” and letters from “A” to “F” are used.
- It means, in total, hexadecimal system has 10 numbers and 6 alphabets.
- Therefore, the base used for hexadecimal numbering system is 16.
Decimal number system:
- In decimal system, the numbers from “0” to “9” are used.
- It means, in total, decimal system has 10 numbers.
- Therefore, the base used for decimal number system is 10.
Program Plan Intro
d.
Decimal number system:
- In decimal system, the numbers from “0” to “9” are used.
- It means, in total, decimal system has 10 numbers.
- Therefore, the base used for decimal number system is 10.
BCD number system:
- Binary Coded Decimal (BCD) refers to a section of binary encodings of decimal numbers.
- Each decimal number will be represented by a fixed number of bits such as four or eight.
- BCD has an advantage of representing each decimal number in four bit pattern. This is also called as “8421” encoding.

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!

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”.
