java - 如何将 Writer 转换为字符串

Question

 Writer writer = new Writer();
 String data = writer.toString();/* the value is not casting and displaying null...*/

还有其他方法可以将写入器转换为字符串吗？

Answer 1

如果我想用它制作一个字符串，我会使用专门的作家。

Writer writer = new StringWriter();
String data = writer.toString(); // now it works fine
