Log4j – Logging framework in JavaInterview Questions in JavaInput/output programming involves reading and writing to files, sockets, console etc.
For example — System.in is a standard input stream (Keyboard) and System.out is the standard output stream (console). Below image shows how a typical Java application reads data from InputStream of file, console or socket and writes to OutputStream of other file, socket or console.
Below images show important classes and interfaces required for I/O programming in Java.
