Usage: javac <options> <source files>

Are you trying to run your first Java program via Windows Command Prompt or macOS Terminal and unable to run because of the above error, there are few things that can go wrong,

• Do you have file available at the location where you are running the javac command. If the file is not found you can get this error. Do dir and check if the file is available in this location.
• Make sure that the file extension is provided correctly i.e. .java
• Also be sure the name the file specified matches with the case in the command (case-sesitivity).
• Make sure the location where you are running this file has permissions.

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }

}

If you are able to find the javac command that indicates that your JAVA_HOME is set properly, it's just the file is not accessible.
