如何克隆CharArrayWriter？

Question

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!!

Answer 1

没有克隆方法，但您可以使用writeTo方法。

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

Answer 2

CharArrayWriter不可复制。根据您的实际要求，您可以执行以下操作：

CharArrayWriter y = new CharArrayWriter();
y.write( x.toCharArray() );

这基本上是一回事。
