Create a class named Person that has the following properties encapsulated:

• idNumber
• firstName
• lastName
• address
• mobile

Create a constructor that accepts only the first 3 properties. Also, have for all properties the corresponding getters and setters and in addition the following methods:

• getName where it returns the first and last name of Person together separated by a space
• toString which displays the Person's data as follows:

Person {
ID Number: ...
First Name: ...
Last Name: ....
Address: ....
Mobile: ...
}

Then create a subclass named Student that has the following properties encapsulated:

• program
• entryYear
• currentYear

The variable entryYear should only take integer values between the years 2000 and 2050. The variable currentYear shall only take values between 1 and 6.

Build a constructor that accepts only the first 3 properties of Person and the first 3 properties of Student. Have also for all properties, the corresponding getters and setters and in addition the following methods:

• getStatus where it returns the student's name, program, entryYear, and currentYear
• toString which displays all the Student's details using also the toString of Person

Then create a subclass named Staff that has the following properties encapsulated:

• school
• salary

The variable salary should only take floating-point values between 0 and 10000.

Build a constructor which accepts only the first 3 properties of Person and the first 2 properties of Staff. It should also have for all properties, the corresponding getters and setters and in addition the following methods:

• toString which displays all elements of Staff using both toString of Person

Finally, build a program (main) in which the classes Student and Staff are used. That is, create two objects, a Student and a Staff and call the toString() methods for each object.
