(Java)Convert the QuartsToGallons program to an interactive application. Instead of assigning a value to the number of quarts, accept the value from the user as input. class
{
public static void main(String[] args)
{
// Modify the code below
final int QUARTS_IN_GALLON=4;
int quartsNeeded=18;
int gallonsNeeded; int extraQuartsNeeded; gallonsNeeded=quartsNeeded/QUARTS_I N_GALLON; extraQuartsNeeded=quartsNeeded%QUAR TS_IN_GALLON;
System. out. println("A job that needs " + quartsNeeded + " quarts requires " + gallonsNeeded + " gallons plus " + extraQuartsNeeded + " quarts");

}
}

import java.util.Scanner;

public class

{

public static void main(String[] args)

{

Scanner scan = new Scanner(System.in);

final int QUARTS_IN_GALLON=4;

int quartsNeeded=0;

System.out.println("How many quarts do you need?");

quartsNeeded = scan.nextInt();

int gallonsNeeded, extraQuartsNeeded;

gallonsNeeded=quartsNeeded/QUARTS_IN_GALLON;  

extraQuartsNeeded=quartsNeeded%QUARTS_IN_GALLON;

System.out.println("A job that needs " + quartsNeeded + " quarts requires " + gallonsNeeded + " gallons plus " + extraQuartsNeeded + " quarts");

}

}

I hope this helps!

To modify a program is to rewrite the program in another way.

In order to make the program an interactive program, we have to remove the following program statement:

final int QUARTS_IN_GALLON=4;

The above program statement assigns 4 to the variable QUARTS_IN_GALLON.

This means that:

Each time the program is run, the value of QUARTS_IN_GALLON is always 4.

Next, we replace the statement with:

Scanner input = new Scanner(System.in)

int QUARTS_IN_GALLON;

QUARTS_IN_GALLON = input.nextInt();

So, the complete modified program is:

class {

public static void main(String[] args){

Scanner input = new Scanner(System.in)

int QUARTS_IN_GALLON;

QUARTS_IN_GALLON = input.nextInt();

int quartsNeeded=18;

int gallonsNeeded; int extraQuartsNeeded; gallonsNeeded=quartsNeeded/QUARTS_IN_GALLON; extraQuartsNeeded=quartsNeeded%QUARTS_IN_GALLON;

System.out.println("A job that needs " + quartsNeeded + " quarts requires " + gallonsNeeded + " gallons plus " + extraQuartsNeeded + " quarts");

}

}
