public class SimpleCar {
   
   // Number of miles driven
   private int miles;
   
   public SimpleCar(){
      miles = 0;

   public void drive(int dist){
      miles = miles + dist;
   }
 
   public void reverse(int dist){
      miles = miles - dist;
   }

      return miles;
   }

   public void honkHorn(){

**LAB ACTIVITY** **26.5.1: LAB: Simple car** **Current file: LabProgram.java** ```java import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); /* Type your code here. */ } } ``` ### Explanation This Java program snippet sets up the starting framework for a lab activity titled "Simple car." The program uses `java.util.Scanner` to handle input from the user. - **Line 1**: Imports the `Scanner` class from the `java.util` package, allowing the program to read input. - **Line 3**: Declares a public class named `LabProgram`. - **Line 4**: Defines the `main` method, which serves as the entry point for the Java application. It accepts a string array `args` as an argument. - **Line 5**: Initializes a `Scanner` object named `scnr` to read from the standard input stream (`System.in`). - **Lines 7-8**: Comments provide a placeholder for where additional code should be typed. This basic structure is ideal for building programs that require user input.

Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: - Drives input number of miles forward - Drives input number of miles in reverse - Honks the horn - Reports car status The `SimpleCar` class is found in the file `SimpleCar.java`. Ex: If the input is: ``` 100 4 ``` the output is: ``` beep beep Car has driven: 96 miles ```
