A FileInputStream obtains input bytes
from a file in a file system. What files
are available depends on the host environment.
FileInputStream is meant for reading streams of raw bytes
such as image data. For reading streams of characters, consider using
FileReader.
extends
java.io.File, java.io.FileDescriptor, java.io.FileOutputStream, java.nio.file.Files.newInputStream
@apiNote
To release resources used by this stream close should be called
directly or by try-with-resources. Subclasses are responsible for the cleanup
of resources acquired by the subclass.
Subclasses that override finalize in order to perform cleanup
should be modified to use alternative cleanup mechanisms such as
java.lang.ref.Cleaner and remove the overriding finalize method.
@implSpec
If this FileInputStream has been subclassed and the close
method has been overridden, the close method will be
called when the FileInputStream is unreachable.
Otherwise, it is implementation specific how the resource cleanup described in
close is performed.
