Write a program 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 gallons plus 2 quarts.

// package

import java.util.*;

// class definition

class Main

{

   //main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

   // variables    

   final int q_in_gallon = 4;

      int no_of_q;

      int no_of_g;

      int q_need;

      // object to read input

      Scanner kb = new Scanner(System.in);

      System.out.print("Enter quarts needed: ");

      // read the number of quarts

      no_of_q = kb.nextInt();

      // find number of gallons

      no_of_g = no_of_q / q_in_gallon;

      // rest of quarts

      q_need = no_of_q % q_in_gallon;

      // print the result

      System.out.println("A job that needs " + no_of_q + " quarts requires " + no_of_g +" gallons plus " + q_need + " quarts.");

   }catch(Exception ex){

       return;}

}

}

Explanation:

Declare and initialize a variable q_in_gallon with 4.Then read the quarts needed from user.Find the number of gallons by dividing quarts with q_in_gallon.Then  find the rest of quarts.Print them into new line.a

Output:

Enter quarts needed: 18                                                                                                    

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