Question

JAVA...

QUESTION 3 IS A CONTINOUS TO Q2 CAN YOU SEND THE CODE SEPARATELY FOR EACH Q , I BE SO THANKFUL

Q2.

Implement a program to store the applicant’s information for a visa office. You need to implement the following:

A super class called Applicant, which has the following instance variables:

• A variable to store first name of type String.
• A variable to store last name of type String.
• A variable to store date of birth, should be implemented as another class to store day, month and year.
• A variable to store number of years working of type integer.
• A variable to store name of company where the applicant works.
• A variable to store average personal bank account balance for last six months of type double.

The class should have the following methods:

• A constructor that sets the instance variables
• A set method for each instance variable
• A get method for each instance variable
• A toString to display class information

An applicant can be self employed or employed. For each type of applicants a sub class should be implemented. Self Employed that inherits from the super class and has the following instance variables:

• A variable to store capital of business of type double.
• A variable to store average Business bank account balance for the last six months.
• A variable to store number of employees in the business of type integer.

The class should have the following methods:

• A constructor that sets the instance variables
• A set method for each instance variable
• A get method for each instance variable
• A toString to display class information

A sub class Employed that inherits from the super class and has the following instance variables:

• A variable to store salary of type double.
• A variable to store title of type String.

The class should have the following methods:

• A constructor that sets the instance variables
• A set method for each instance variable
• A get method for each instance variable
• A toString to display class information

Implement a test function that lists the information of the applicant using toString() method.

Sample output:

Applicant 1:

Name: Mohammed Ali

Date of Birth: 01/Jan/1970

Works at: ABC Co. for 3 years

Salary: 2000KD

Average Account Balance:

1500KD

Title: Sales Manager

              

Applicant 2:

Name: John Smith

Date of Birth: 01/Mar/1975

Owns: XYZ Co. for 10 years

Capital: 50000KD

Average Account Balance:

2000KD

Average Co. Account Balance:

2500KD

Number of Employees: 10

Q3.

For the previous question apply some changes to add a functionality that evaluates if the applicant is Approved, Rejected or Needs Extra Review.

Change Applicant class to an abstract class and add an abstract method called evaluate().

In SelfEmployed class, evaluate() method is implemented as follows:

If capital of company is less than 5000 then the application is rejected.

If the average company account balance is less than 3000 and the capital is less than 10,000 then the application is rejected.

If the average company account balance is between 3000 and 5000, the capital is between 10,000 and 15,000 then the application needs extra review.

If the average company account balance is less than 3000, and the number of employees is less than 15 then the application needs extra review.

If the average company account balance is less than 3000, and the average personal account balance is less than 1000 then the application needs extra review.

In all other cases the application is Approved.

In Employed class, evaluate() method is implemented as follows:

If the average account balance is less than 1000 and the salary is less than 1000 then the application is rejected.

If the salary is less than 1000 and the number of years of employment is less than 3 then the application is rejected.

If the average account balance is between 1000 and 1500, and the number of years of employment is less than 3 then the application needs extra review.

In all other cases the application is Approved.

Applicant 1:

Name: Mohammed Ali

Date of Birth: 01/Jan/1970

Works at: ABC Co. for 3 years

Title: Sales Manager
Evaluation:Approved

Applicant 2:
Name: John Smith
Date of Birth: 1/Mar/1975
Owns: XYZ Co. for 10 years
Capital: 50000.0KD
Average Account Balance: 2000.0KD
Average Co. Account Balance: 2500.0KD
Number of Employees: 10
Evaluation:Review

Note: There is a mistake in your code output of Q3. In the problem the following statement is given:

"If the average company account balance is less than 3000, and the number of employees is less than 15 then the application needs extra review."

Now see the data for Applicant 2, company account balance 2500 and the number of employees is 10.

In your sample output "Rejected" is given for Applicant 2, but it should be "Review" as per given instruction.
