Examples of java.io.StringWriter

java.io.StringWriter
A character stream that collects its output in a string buffer, which can then be used to construct a string.
Closing a StringWriter has no effect. The methods in this class can be called after the stream has been closed without generating an IOException. @version 1.26, 05/11/17 @author Mark Reinhold @since JDK1.1
