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.
Returns an array containing all of the exceptions that were
suppressed, typically by the try-with-resources
statement, in order to deliver this exception.
Constructs a FileNotFoundException with the
specified detail message. The string s can be
retrieved later by the
Throwable.getMessage()
method of class java.lang.Throwable.

This exception is thrown by `FileInputStream`, `FileOutputStream`, and `RandomAccessFile` constructors. It has two constructors: one creates the exception with a `null` message, and the other allows providing a custom detail message. It inherits methods like `getMessage()` to retrieve the error detail, `printStackTrace()` to print the stack trace, and `addSuppressed()` to add exceptions that were suppressed.\n"]]
