A random-access file is a file in which the user or programmer can read and write data to the file at any location (hence the name random) simultaneously. A random-access file behaves like a large array of bytes. To navigate through the file, there is a file pointer which can be moved to the desired […]
In Java we can store objects as a byte stream and store it in files or send it over a network. The process of converting an object to a byte stream is serialization and the reverse process of converting a byte stream to an object is called deserialization. In Java programs, we can achieve […]
The character stream or textual I/O classes deals with reading characters or writing characters to a target or destination stream. They can be used for reading or writing characters to text-based files like XML, HTML, JSON etc. The character stream abstract base classes are Reader and Writer. The input character stream class hierarchy is […]
The byte stream or binary classes in Java are used to read and write data in the form of bytes to files like images, videos, etc. The byte stream abstract base classes are InputStream and OutputStream. The input byte stream class hierarchy is shown in the below figure. The description of these input byte […]
Introduction to Java IO The Java Input Output (IO) API enables Java programs to read data from and write data to file system or disk and to other devices through a network connection. The Java I/O API was introduced in the initial version of Java in the mid-90s. In Java SE 1.4, Java NIO was […]
