Deprecated: The finalize method has been deprecated and will be removed. Subclasses that override finalize in order to perform cleanup should be modified to use alternative cleanup mechanisms and to remove the overriding finalize method. When overriding the finalize method, its implementation must explicitly ensure that super.finalize() is invoked as described in Object.finalize. See the specification for Object.finalize() for further information about migration options.

Overriding: java.lang.Object

Ensures that the close method of this file input stream is called when there are no more references to it. The finalize method does not call close directly.

Exceptions:

IOException

if an I/O error occurs.

java.io.FileInputStream.close()

@apiNote To release resources used by this stream close should be called directly or by try-with-resources.
@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.
