Question

在Java 1.5中，如何克隆java.io.CharArrayWriter的實例？

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

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

Answer 1

沒有clone方法，但你可以用writeTo方法。

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

Answer 2

CharArrayWriter不可複製。根據您的實際需求，你可以做類似：

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

基本上是同樣的事情。
