A
Closeable
is a source or destination of data that can be closed.
The close method is invoked to release resources that the object is
holding (such as open files).- Since:

Method Details
-
close
Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.As noted in
AutoCloseable.close()
, cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark theCloseable
as closed, prior to throwing theIOException
.- Specified by:
close
in interfaceAutoCloseable
- Throws:
IOException
- if an I/O error occurs
