What do you know about the RandomAccessFile class?

RandomAccessFile provides the ability to read and write data at any location in a file. Unlike streams, it is not a subclass of InputStream or OutputStream.

Key features:

• Positioning: Allows moving within the file, setting the current position using the seek() method.
• Access modes: Opened with a specific access mode ("r", "rw", "rws", "rwd").
• Read and write: Supports reading and writing primitive data types, strings, and byte arrays.
• File length: Can get the current file length (length()) and set it (setLength()).

Example of opening a file for reading and writing:

// RandomAccessFile
RandomAccessFile file = new RandomAccessFile("my_file.txt", "rw");
// ... work with the file
file.close();

Example of moving within a file and reading:

// RandomAccessFile
RandomAccessFile file = new RandomAccessFile("my_file.bin", "r");
file.seek(100); // Move to the 100th byte
byte b = file.readByte(); // Read one byte
file.close();

Example of writing to a file:

// RandomAccessFile
RandomAccessFile file = new RandomAccessFile("my_output.txt", "rw");
file.writeBytes("Hello, world!"); // Write string
file.close();

Access modes:

Mode	Description
"r"	Open for reading.
"rw"	Open for reading and writing.
"rws"	Open for reading and writing with synchronous update of content and metadata at OS level.
"rwd"	Open for reading and writing with synchronous content update at OS level (metadata may be delayed).
