public interface Closeable

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

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.

Throws:

IOException - if an I/O error occurs
