Java File Handling is essential for developers to create, read, update, and delete files, ensuring data persistence and efficient data management. It involves stream management, error handling, and file pointer management. Advanced techniques like the java.nio.file package and Object Streams enhance file manipulation, making it crucial for handling large data volumes and complex file operations.
