Java FileChannel is a class that provides a mechanism for reading, writing, and manipulating files in a non-blocking, high-performance manner. It is part of Java's java.nio package and offers features like memory-mapped files and asynchronous file operations. Introduced in Java 2007 with Java 7, FileChannel is widely used for file I/O tasks where performance and scalability are critical, such as in large-scale file processing or data storage systems.
