Question

Write a Java class that declares a named constant to hold the number of quarts in a gallon (4). Also declare a variable to represent the number of quarts needed for a painting job, and assign an appropriate value-for example, 18. Compute and display the number of gallons and quarts needed for the job. Display explanatory text with the values-for example, A job that needs 18 quarts requires 4 gal Ions plus 2 quarts. Save the class as QuartsToGallons.java. Convert the QuartsToGallons class to an interactive application. Instead of assigning a value to the number of quarts, accept the value from the user as input. Save the revised class as QuartsToGallonsInteractive.java.

Explanation / Answer

a)

public class QuartsToGallons {

   public static void main(String[] args) {
       //Declaring a named Constant
       final int no_of_Quarts_in_gallon=4;
      
       //Declaring a integer variable
       int no_of_quarts=18;
      
       //This statement will convert total quarts into gallons and quarts.
       System.out.println("A job that needs "+no_of_quarts+" quarts requires "+no_of_quarts/no_of_Quarts_in_gallon+" gallons plus "+no_of_quarts%no_of_Quarts_in_gallon+" quarts.");

   }

}

Output:

A job that needs 18 quarts requires 4 gallons plus 2 quarts.

package org.students;

import java.util.Scanner;

public class QuartsToGallons {

   public static void main(String[] args) {

       //Declaring a named Constant
               final int no_of_Quarts_in_gallon=4;
      
       //Declaring a integer variable
               int no_of_quarts = 0;
      
               //Scanner object is used to get the inputs entered by the user
               Scanner sc=new Scanner(System.in);

//Getting the no of quarts entered by the user
               System.out.print("Enter no of quarts :");
               no_of_quarts=sc.nextInt();

               //This statement will convert total quarts into gallons and quarts.
               System.out.println("A job that needs "+no_of_quarts+" quarts requires "+no_of_quarts/no_of_Quarts_in_gallon+" gallons plus "+no_of_quarts%no_of_Quarts_in_gallon+" quarts.");
      
   }

}
