FileNotFoundException

  • FileNotFoundException signals that a file could not be opened because it does not exist or is inaccessible.

  • It's thrown by FileInputStream, FileOutputStream, and RandomAccessFile constructors when the target file isn't found or accessible.

  • This exception provides two constructors: one with a detailed message and one without.

  • FileNotFoundException inherits methods from IOException and Throwable for handling and inspecting the exception.

public class FileNotFoundException extends IOException

Signals that an attempt to open the file denoted by a specified pathname has failed.

This exception will be thrown by the FileInputStream, FileOutputStream, and RandomAccessFile constructors when a file with the specified pathname does not exist. It will also be thrown by these constructors if the file does exist but for some reason is inaccessible, for example when an attempt is made to open a read-only file for writing.
