java - 如何克隆CharArrayWriter？

在Java 1.5中，如何克隆java.io.CharArrayWriter的实例？

CharArrayWriter x = new CharArrayWriter(200);
x.write("foo bar bob");

CharArrayWriter y = x.clone();   //  Object.clone() is not visible!!

谢谢，

最佳答案

没有克隆方法，但是可以使用writeTo方法。

CharArrayWriter copy = new CharArrayWriter(x.size());
x.writeTo(copy);
