Question

Write a class FinancialAidApplicant which describes an applicant for financial aid and will be used by a financial aid officer.

Qualification is based on annual household income and the number of people in the household. If the household income is less than $20,000, the applicant automatically qualifies regardless of how few people are in the household. If the household income is at least $20,000 but at most $60,000 and there are 4 or more people in the household, the applicant qualifies. If the household income is more than $60,000 but at most $150,000 and there are 6 or more people in the household, the applicant qualifies. For all other cases, the applicant does not qualify.

A tester program is provided to you in Codecheck, but there is no starter code for class FinancialAidApplicant.

You should declare static constants for the numbers mentioned above.

The class has a constructor that takes a String, a double, and an int as parameters

public FinancialAidApplicant(String name, double income, int numberOfPeople)

It also has four methods:

• public String getName() Gets the applicant's name.

• public void setNumberOfPeopleInHousehold(int people) Sets number of people in the household

• public void setHouseholdIncome(double income) Sets a new household income

• public boolean qualifies() Returns true if the applicant qualifies and false

Method qualifies should have one if-else if-else statement instead of multiple if statements.

Code check:

public class FinancialAidApplicantTester
{
   public static void main(String[] args)
   {
       FinancialAidApplicant applicant =
          new FinancialAidApplicant("Joe Programmer",19999, 1);
         
       System.out.printf("The name of the applicant: %s.%n", applicant.getName());
       System.out.println("Expected: The name of the applicant: Joe Programmer.");

       System.out.println(applicant.qualifies());
       System.out.println("Expected: true");
       
       applicant.setHouseholdIncome(20000);
       applicant.setNumberOfPeopleInHousehold(3);
       System.out.println(applicant.qualifies());
       System.out.println("Expected: false");
       
       applicant.setNumberOfPeopleInHousehold(4);
       System.out.println(applicant.qualifies());
       System.out.println("Expected: true");

       applicant.setHouseholdIncome(60000);
       applicant.setNumberOfPeopleInHousehold(4);
       System.out.println(applicant.qualifies());
       System.out.println("Expected: true");
       
       applicant.setNumberOfPeopleInHousehold(3);
       System.out.println(applicant.qualifies());
       System.out.println("Expected: false");
       
       applicant.setHouseholdIncome(60001);
       applicant.setNumberOfPeopleInHousehold(6);
       System.out.println(applicant.qualifies());
       System.out.println("Expected: true");
       
       applicant.setNumberOfPeopleInHousehold(5);
       System.out.println(applicant.qualifies());
       System.out.println("Expected: false");
       
       applicant.setHouseholdIncome(150000);
       applicant.setNumberOfPeopleInHousehold(6);
       System.out.println(applicant.qualifies());
       System.out.println("Expected: true");
       
       applicant =
          new FinancialAidApplicant("Mary Rowe",150001, 10);
 
       System.out.printf("The name of the applicant: %s.%n", applicant.getName());
       System.out.println("Expected: The name of the applicant: Mary Rowe.");

       System.out.println(applicant.qualifies());
       System.out.println("Expected: false");
   }
}

PROGRAM:

Please find below the test class as per the given requirements:

File Name: FinancialAidApplicant.java

public class FinancialAidApplicant {

                //constants for income and members

                private static final int QUALIFYING_INCOME = 20000;//a constant for minimum income

                private static final int QUALIFYING_INCOME_II = 60000;//a constant for income 60000

                private static final int MAX_INCOME = 150000;//a constant for income 150000

               

                //local private data members of the class

                private String name;

                private double income;

                private int numberOfPeople;

               

                public FinancialAidApplicant(String name, double income, int numberOfPeople) {//parameterized constructor

                                //set private data members as per the value provided in parameter

                                this.name=name;

                                this.income=income;

                                this.numberOfPeople=numberOfPeople;

                }

                public String getName() { //Gets the applicant's name.

                                return name;

                }

                public void setNumberOfPeopleInHousehold(int people) { //Sets number of people in the household

                                numberOfPeople= people;

                }

                public void setHouseholdIncome(double income) {// Sets a new household income

                                this.income = income;

                }

                public boolean qualifies() {//Returns true if the applicant qualifies and false

                                if(income<QUALIFYING_INCOME) {

                                                return true; //income is less than 20000, no need to consider people, return true

                                }

                                else if(income>=QUALIFYING_INCOME && income<=QUALIFYING_INCOME_II && numberOfPeople>=4) {

                                                return true;//people are 4 or more and income in between 20000 to 60000(including)

                                }

                                else if(income>QUALIFYING_INCOME_II && income <=MAX_INCOME && numberOfPeople >=6){

                                                return true;//people are 6 or more and income is more than 60000 to 150000(including)

                                }

                                else {//for all other cases

                                                return false;

                                }//end else part

                }//end method

}
