Examples of java.io.PrintWriter.checkError()

java.io.PrintWriter.checkError()
Answers a boolean indicating whether or not this PrintWriter has encountered an error. If so, the receiver should probably be closed since further writes will not actually take place. A side effect of calling checkError is that the target Writer is flushed. @return boolean has an error occurred in this PrintWriter.
