File handling in Java refers to the process of creating, reading, writing, updating, and deleting files stored on secondary storage. Java provides a rich set of classes in the `java.io` and `java.nio.file` packages to perform input and output (I/O) operations efficiently. The `java.io` package includes classes such as `File`, `FileReader`, `FileWriter`, `BufferedReader`, `BufferedWriter`, `InputStream`, `OutputStream`, and `PrintWriter`. These classes allow Java programs to interact with files and other I/O devices such as keyboards, printers, and network connections. Input and Output (I/O) operations in Java are stream-based. An input stream reads data from a source, while an output stream writes data to a destination. Java supports two major categories of streams: byte streams and character streams. Byte streams, represented by classes such as `FileInputStream` and `FileOutputStream`, are suitable for binary data like images and audio files. Character streams, represented by `FileReader` and `FileWriter`, are used for handling text files because they support Unicode characters. The `File` class, available in the `java.io` package, represents the pathname of a file or directory. It does not directly read or write data but provides methods to create, delete, rename, and obtain information about files and directories. The `File` object acts as an abstraction of file system paths. Some commonly used methods of the `File` class are: * `createNewFile()`
