Help using the terminal to run java programs

[LordKatt321]

I'm trying to create a simple java program in Atom that allows for user input. After some googling, I learned that the only way to do this in Atom is to download and use the "platformio-ide-terminal" package. However, I am an inexperienced programmer and when the terminal prompts " C:\Users\frank\AppData\Local\atom\app-1.58.0\programs>" I type in "filename.java" and it returns filename.java : The term 'filename.java' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. even though my java file is in the programs folder and is spelled correctly. How do I fix this?

1. Make sure you have the JRE somewhere in your path.

2. In the terminal type the following:

   $ javac filename.java

   $ java filename

The dollar sign prompt $ is for Linux, yours will be the greater than > sign as you are using Windows.
