title: Compiling four java files within one package using javac
body: <p>I have four java files in my folder. They are all in the same package. Here's the package declaration<br>
  <code>package com.osama.GHide</code> </p>
  
  <p>All of these classes are in the same package. I want to know how can I compile them using <code>javac</code> (i mean i do not know how to compile multiple files that are using each other). And once that is done how do I launch then using <code>java</code> command in the CLI? here are the file names.<br>
  <code>EnteringPoint.java</code> 
  <code>HidingProcess.java</code> 
    <code>ListFiles.java</code></p>
