Question

Java Program

using inheritance, create a program that will take input from the user to answer this information: (Create a method for home, car, and personal loan) Thanks!

montly income= 80,000
extra income=30,000
any libality=40,000
total income=80,000+30,000-40,000=?

eligibility for homeloan=total_income*80% for home loan
eligibility for car loan=total_income*60% for carloan
eligibility for personal loan=total_income*70% for personal loan

Answer 1

PersonIncome.java

//super class
public class PersonIncome {
   //member variables
   private double monthlyIncome;
   private double extraIncome;
   private double liability;
  
   //constructor
   public PersonIncome(double monthlyIncome, double extraIncome, double liability)
   {
       this.monthlyIncome = monthlyIncome;
       this.extraIncome = extraIncome;
       this.liability = liability;
   }
  
   //method that calculates and returns total income
   public double getTotalIncome()
   {
       return this.monthlyIncome + this.extraIncome - this.liability;
   }
}

LoanEligibility.java

public class LoanEligibility extends PersonIncome{
   //constructor
   public LoanEligibility(double monthlyIncome, double extraIncome, double liability)
   {
       //call the super class constructor
       super(monthlyIncome, extraIncome, liability);
   }

   //method that calculates and returns the eligibility for home loan
   public double getEligibleHomeAmount()
   {
       return getTotalIncome() * 80 / 100;
   }

   //method that calculates and returns the eligibility for car loan
   public double getEligibleCarAmount()
   {
       return getTotalIncome() * 60 / 100;
   }

   //method that calculates and returns the eligibility for personal loan
   public double getEligiblePersonalAmount()
   {
       return getTotalIncome() * 70 / 100;
   }
}

TestLoan.java

import java.util.Scanner;

public class TestLoan {

   public static void main(String[] args) {
       //create object to Scanner class to read input from user
       Scanner input = new Scanner(System.in);
      
       double monthlyIncome, extraIncome, liability;
      
       //prompt and read monthly income
       System.out.print("Enter monthly income: $");
       monthlyIncome = input.nextDouble();
      
       //prompt and read extraIncome
       System.out.print("Enter extra income: $");
       extraIncome = input.nextDouble();
      
       //prompt and read extraIncome
       System.out.print("Enter liabilities if any: $");
       liability = input.nextDouble();
      
       //create an object LoanEligibility class
       LoanEligibility loanObj = new LoanEligibility(monthlyIncome, extraIncome, liability);
      
       //get and display home loan
       System.out.println("\nEligibility for home loan: " + loanObj.getEligibleHomeAmount());
       //get and display car loan
       System.out.println("Eligibility for car loan: " + loanObj.getEligibleCarAmount());
       //get and display personal loan
       System.out.println("Eligibility for personal loan: " + loanObj.getEligiblePersonalAmount());
      
       input.close();
   }

}
