 ## Elements of a Java Application

Do not worry, your expectation will be fulfilled by the end of this tutorial. But before we move on, I would like to do through several elements that you need to know to fully understand what you are doing.

You can use these feature only if you are executing a program that is written in a single file. This way of executing your java application does not work if your java code spans more than one file.

 ## Creating a First Java Class
 
 The first step you need to know is that the Java code you are writing is saved in plain text files. In this tutorial, your application will be written in a single text file. Larger applications may require thousands of such files.
 
-Java is an object-oriented language. If this technical term does not mean anything to you, do not worry, all you need to remember at this point is that all the code you write must be held in a Java class.

 ## Preparing the Compilation of your First Class
 
 Compiling is the second step you need to follow after the creation of your first class. It consists of transforming the Java code you wrote in your `MyFirstClass.java` file into another format that can be executed. The result of this transformation will be stored in another file created by the compiler. The name of this file will be `MyFirstClass.class`.
 
-So far the only tool you have been using is a plain text editor. Compiling this class requires a compiler; something you may not have on your computer. Fortunately, you can download this compiler and use it for free. Let me guide you through this process.
