"I know I am required to go to C:\Programefiles\java\jdk." No you're not. It's in the path. You need to go to the directory where your first.java file is *or* provide the full path to the file to the `javac` command. – Federico klez Culloca Sep 14 '20 at 11:12

Your description is a bit confusing but I think your javac tells that it did not find your first.java class.
Verify your javac by simply calling javac in a teminal. If it returns the manual than your installation is correct.
You can try to call the first.java file with absolute path too.

I don't know where your file is, but the command should look like this: `javac c:\path\to\folder\first.java` – danielbene Sep 14 '20 at 13:53
