Java I/O Tutorial: Streams, Readers, and Writers Explained Simply

When we work with any programming language, handling data is one of the most important tasks. In Java, this is done using the concept of Input and Output (I/O). This Java I/O Tutorial will help you understand how data can be read from a source or written to a destination in simple ways.

Java I/O mainly deals with reading and writing data from different sources like files, keyboards, or networks. The “Input” means taking data into the program, while “Output” means sending data out of the program. For example, reading from a file is input, and writing into a file is output.

In this Java I/O Tutorial, you will also come across important components such as streams, readers, and writers. Streams in Java act like channels through which data flows. There are two types of streams – byte streams and character streams. Byte streams are used to handle raw binary data, while character streams are used for text data.

Another important part of Java I/O is file handling. With the help of classes and methods, Java allows you to create, read, write, and manage files easily. This makes it very useful for real-life applications like saving user details, processing records, or transferring information.

Learning Java I/O is essential for anyone who wants to become a skilled Java developer. It builds the foundation for working with files and data efficiently.
