 public interface Closeable extends AutoCloseable ACloseableis 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 Detail- 
closevoid close() throws IOExceptionCloses 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 interface- AutoCloseable
- Throws:
- IOException- if an I/O error occurs
