This
interface defines a flush(
) method and is implemented by
flushable objects such as java.io streams. This
interface was added in Java 5.0 to enable
java.util.Formatter to distinguish
java.lang.Appendable objects that need to be
flushed (such as streams) from those that do not (such as
StringBuilder objects). See also
Closeable.
