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:
- 1.5
Method Summary
Modifier and Type | Method | 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
.

IOException
