Java File Handling Programs

Java is a programming language that can create applications that work with files. Files are containers that store data in different formats, such as text, images, videos, etc. Files can be created, read, updated, and deleted using Java.

Java provides the File class from the java.io package to handle files. The File class represents a file or a directory in the file system. It has many methods to perform various operations on files, such as checking if a file exists, creating a new file, deleting a file, getting its name or size, etc.

In this article, we present a comprehensive list of Java file-handling programs with output and explanations.
