新 PrintWriter(新 BufferedWriter(新 PrintWriter(s.getOutputStream, true)))
我想知道在 Java 中是否可以做到
new PrintWriter(new BufferedWriter(new PrintWriter(s.getOutputStream, true)))
s 是 Socket？因为不可能从输出流创建 BufferedWriter，所以我用 PrintWriter 包装了输出流。但我想缓冲打印输出，所以我用 BufferedWriter 包装它。但最终我想使用 printWriter 进行打印，所以我用 PrintWriter 再次包装它。这在 Java 中合法吗？谢谢！
I am wondering is it possible to do
new PrintWriter(new BufferedWriter(new PrintWriter(s.getOutputStream, true)))
in Java where s is a Socket? Because it's impossible to create a BufferedWriter from an outputstream, I have wrapped the outputstream with a PrintWriter. But I want to buffer my print outs, so I wrap it with a BufferedWriter. But eventually I want to print using printWriter so I wrap it again with a PrintWriter. Is this legal in Java? Thanks!

这是合法的，但很笨拙。您可以改为缓冲
OutputStream：另外看看
new PrintWriter(OutputStream, boolean)的实现：缓冲已经存在了！
It is legal but clumsy. You can buffer
OutputStreaminstead:Also have a look at the implementation of
new PrintWriter(OutputStream, boolean):buffering is already there!
OutputStreamWriter是您正在寻找的类。只需向其传递一个流和一个编码，例如"UTF-8"。OutputStreamWriteris the class you're looking for. Just pass it a stream and an encoding, for example"UTF-8".
