public interface Closeable
extends AutoCloseable
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).

Description
void
close()
Closes this stream and releases any system resources associated
with it.
Method Detail
close
void close()
throws IOException
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 the Closeable as closed, prior to throwing
the IOException.
Specified by:
close in interface AutoCloseable
Throws:
IOException - if an I/O error occurs
