What is the correct way to "empty" a StringWriter in Java so that I can reuse the StringWriter without having to create a new one? Neither StringWriter.flush() nor StringWriter.close() seem to have the desired effect.
在Java中“清空”StringWriter的正确方法是什么,以便我可以重用StringWriter而无需创建新的StringWriter? StringWriter.flush()和StringWriter.close()似乎都没有所需的效果。
