![**LAB ACTIVITY**
**26.5.1: LAB: Simple car**
**Current file: LabProgram.java**

public class LabProgram {
public static void main(String[] args) {

### 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faad9e4ed-ed50-4fe3-96ca-72ed3d364f6f%2Ff1b50906-fa1a-47a9-815e-1f4e3d1ccb27%2F8lbfym_processed.png&w=3840&q=75)

![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
