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).
- Since:

Method Summary
Modifier and Type Method Description voidclose()Closes this stream and releases any system resources associated with it.
-
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 theCloseableas closed, prior to throwing theIOException.- Specified by:
closein interfaceAutoCloseable- Throws:
IOException- if an I/O error occurs
