Java program works from the IDE but not the command line

Question

I've been working a simple program, and when I run it from the IDE it works 100% as intended, but when I try to compile it using javac from the command line it comes up saying with this:

C:\Users\Lukasz\Documents\NetBeansProjects\NetBeansTest\src\netbeanstest>javac M
ain.java
Main.java:19: error: cannot find symbol
            MainFrame myFrame = new MainFrame();
            ^
  symbol:   class MainFrame
  location: class Main
Main.java:19: error: cannot find symbol
            MainFrame myFrame = new MainFrame();
                                    ^
  symbol:   class MainFrame
  location: class Main
2 errors

However I am unsure what could possibly missing as all of the files are in the same directory. This is what my main looks like:

public class Main {
    public static void main(String[] args) {
            MainFrame myFrame = new MainFrame();
            myFrame.setVisible(true);
    }
}

As you can see it's nothing complicated. Line 19 where the error is MainFrame myFrame = new MainFrame(); but I do not see what could be wrong with it , as it compiles file in the IDE.

Any help here would be very appreciated.

Did you compile your MainFrame class ?

You are compiling Main.java, which has a dependency on MainFrame.java file.

Try compiling and creating a .class file for MainFrame before compiling Main.java

To compile a directory use :

javac dir1/*.java

You are only compiling one file. The compiler hasn't been informed about the existence of the file containing the MainFrame class.

That would make sense, how would I go about easily compiling everything in the folder?
