Expert Solution & Answer
Chapter 8, Problem 8.48RQ
Explanation of Solution
Virtualization:
- When a hardware and software are used in simulating other hardware resources is called as virtualization.
- When the computer hardware or software resources are created virtually; virtual version includes creating hardware platforms, storage devices, and network resources.
- Virtualization reduces the space occupied by the resources, hardware maintenance cost, and software licensing cost.
- When hardware resources are shared with one or more computer it is called as virtualization.
- When a physical computer hosts one or more virtual computers it is called as virtual machine...

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!
