What do these errors mean?

Question

I was making a program in Java and encountered some errors. Here is a link to a screenshot since I doubt it is possible to insert images into these: https://imgur.com/a/xqx9r

Answer 1

The scope of the variable commands is only visible within the main method itself and you have 2 ways to solve it:-

✅ Move the definition of commands outside of the method as a class variable so every method in the class can access to it.

✅ Pass it into the checkValid method as parameter

Hopefully it helps! 😉

Answer 2

Hi Mia, you can make your code public and then post a link to the code. That way people can run the code, see the error and hopefully help you debug it.

I cannot view your link to see the screenshot as I'm at work and it gets blocked.

Answer 3

Okay.
