Java 11 Programming for Beginners 4.5: Managing the Input/OutputJava 11

This video tutorial covers Java I/O, focusing on input and output management using various classes like FileInputStream, FileOutputStream, and BufferedReader. It introduces new I/O (nio) for better error detection and memory usage. The tutorial demonstrates enhancing a translator to read from System.in using Scanner and converting text to Pig Latin. It also covers reading from files, handling exceptions, and managing streams with try-catch and try with resource constructs.
