Question

(*Use Netbeans or hardcode if you choose to use a GUI over console app.)

Write a java program that demonstrates recursion. This program can be in a java GUI frame or as a console application. On this one it is up to you. (It would probably work better as a console program for this particular program.)

The input for this program is a number of boxes. Ask the user for this with a textbox or a prompt on the command line.

Demonstrate recursion with a function called LoadTruck() that takes a number of boxes to be packed as a parameter. This function should print “Truck Loaded” and subtract 5 from the number of boxes and recursively call itself until there are less than 5 boxes. That time through it should print “There are not enough to pack another truck.”

(If you wish to use a GUI, it might be best to “print” the lines by concatenating them onto the text in a textArea along with a newline character. There may be other ways you can think of to do this in a GUI using other controls. Anyway you display the trucks loaded is fine.)

This program must have a recursive method. If you use a loop to load the trucks it will not count for any of the points for this one. This lab is to demonstrate recursion.

Example of output for 23 boxes:

“Truck Loaded”

“Truck Loaded”

“Truck Loaded”

“Truck Loaded”

“There are not enough to pack another truck.”

Thanks for the question, here is the console application .

========================================================================

import java.util.Scanner;

public class Truck {

    public static void LoadTruck(int boxes){
        if(boxes<5){
            System.out.println("There are not enough to pack another truck.");
        }else{
            System.out.println("Truck Loaded");
            boxes-=5;
            LoadTruck(boxes);
        }

    }
    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter the number of boxes you like to load: ");
        int boxes = scanner.nextInt();
      LoadTruck(boxes);
    }
}

Thanks a lot, please do give a thumbs up : )
