public void close() throws IOException Implements java.io.Closeable.close. Doc from java.io.Closeable.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 the `Closeable` as closed, prior to throwing the `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.
