Java FileChannel.read() is a method in the Java FileChannel class that reads data from a file into a ByteBuffer. It is used for file I/O operations when working with large amounts of data, as it provides more control and efficiency than traditional stream-based methods. Introduced in Java 2007 with Java 7, read() is essential for managing file content in applications that require high-performance or memory-mapped file access.
