public interfaceCloseableextendsAutoCloseable
ACloseable 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).

    Modifier and Type
    Method
    Description
    void
    Closes this stream and releases any system resources associated with it.

    • close

      void close() throwsIOException
      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 inAutoCloseable.close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internallymark theCloseable as closed, prior to throwing theIOException.

      Throws:
      IOException - if an I/O error occurs
