<title>File Handling</title>

<introduction>
<p>
File handling is an integral part of programming. Most programming languages have the ability to read from, write to, create, delete, move, and copy files.

In Python, most built-in libraries are available without needing to explicitly import additional packages, but some libraries like <c>math</c> do need to be imported. Consider the following.

Java includes a class called <c>File</c> in the <c>io</c> library. The class can be imported with the following line. Be sure to capitalize <c>File</c>.
Much like the Math class, in order for your program to work with files you need to import classes from libraries. Java includes a class called <c>File</c> in the <c>io</c> library. This class allows you to create File objects, and use its public methods. the following code imports the <c>File</c> class and creates a <c>File</c> object called myFile. for now focus on how the class is imported and used in the program; We will cover the <c>IOException</c> class and <c>createNewFile</c> method later.
