Write a console-based program that accepts a user's message and determines whether it is short enough for a social networking service that does not accept messages of more than 140 characters.

this program calculates and display the distance a vehicle has traveled after each hour of journey. Make sure to use a for loop and have input validation.

To write a console-based program that determines whether a user's message is short enough for a social networking service with a character limit of 140, you can follow these steps:

1. Prompt the user to enter a message.
2. Read the user's input from the console.
3. Use the `length()` function to get the length of the message.
4. Compare the length of the message with the character limit (140).
5. If the length is less than or equal to 140 characters, display a message indicating that the message is short enough.
6. If the length exceeds 140 characters, display a message indicating that the message is too long and needs to be shortened.

Here's an example implementation in Java:

```java
import java.util.Scanner;

public class MessageLengthChecker {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

// Prompt the user to enter a message
System.out.print("Enter your message: ");
String message = scanner.nextLine();

// Calculate the length of the message
int length = message.length();

// Check if the message is short enough
if (length <= 140) {
System.out.println("Message is short enough for the social networking service.");
} else {
System.out.println("Message is too long. Please shorten your message.");
}

scanner.close();
}
}
```

You can compile and run this program to test it with different messages. When prompted, enter your message, and the program will tell you if it's short enough or too long.
