Question

Can I get the answers in Java, please?

Write an application that prompts a user for the number of years the user has until retirement and the amount of money the user can save annually. If the user enters a 0 or a negative number for either value, reprompt the user until valid entries are made. Display the amount of money the user will have at retirement.

The total amount of money the user will have can be calculated with the following equation:

total=numYears∗amountSaved

Example input:

0
5
-2
45

Example output:

How many years until retirement?
Years cannot be 0 or negative. Reenter years: 
How much can you save annually?
Amount cannot be 0 or negative. Reenter amount to save annually: 
If you save $45 for 5 years, you will have $225

Answer 1

import java.util.*;

class Retirement

{

    public static void main(String[] args)

    {

        Scanner sc = new Scanner(System.in);

       

        int numYears;

       

        System.out.println("How many years until retirement?");

       

        // get user input

        numYears = sc.nextInt();

       

        // infinite loop

        while(true)

        {          

            // if input is correct

            if( numYears > 0 )

                break;

           

            System.out.print("Years cannot be 0 or negative. Reenter years: ");

           

            // get user input

            numYears = sc.nextInt();

        }

       

        int amountSaved;

       

        System.out.println("\nHow much can you save annually?");

        

        // get user input

        amountSaved = sc.nextInt();

       

        // infinite loop

        while(true)

        {          

            // if input is correct

            if( amountSaved > 0 )

                break;

           

           System.out.print("Amount cannot be 0 or negative. Reenter amount to save annually: ");

           

            // get user input

            amountSaved = sc.nextInt();

        }

       

        // calculate total amount saved

        int total = numYears * amountSaved;

       

        System.out.println("If you saved $" + amountSaved + " for " + numYears + " years, you will hava $" + total);

    }

}
