Error cannot find symbol scanner scanner new scanner system.in

A classic error!

The error message "cannot find symbol" usually means that the Java compiler is unable to find a class, method, or variable that you're trying to use.

In this case, the error is specifically related to the Scanner class.

Here are a few possible solutions:

1. Make sure you've imported the Scanner class: At the top of your Java file, add the following line:

   import java.util.Scanner;

   This imports the Scanner class from the java.util package, which is where it's defined.

2. Check your Java version: The Scanner class was introduced in Java 5 (also known as Java 1.5). If you're using an older version of Java, you might not have access to this class. You can check your Java version by running the command java -version in your terminal or command prompt.

3. Check your code for typos: Double-check that you've spelled Scanner correctly and that you haven't misspelled any other parts of the code.

4. Make sure you've created a Scanner object correctly: The Scanner class is used to read input from a source, such as the console or a file. You need to create a Scanner object and specify the source you want to read from. For example:

   Scanner scanner = new Scanner(System.in);

   This creates a Scanner object that reads from the system input (i.e., the console).

If you've checked all of these and you're still getting the error, please provide more code context or details about your environment, and I'll do my best to help you troubleshoot the issue!
