The difference between PrintWriter and BufferedWriter

1. PrintWriter's print and println methods can accept parameters of any type, while the write method of BufferedWriter can only accept characters, array of characters, and strings;

2. PrintWriter's Println method automatically adds line wrapping, BufferedWriter needs to display the calling newline method;

3. The PrintWriter method does not throw the exception, if concerns the exception, needs to call the CheckError method to see whether has the unusual occurrence;

4. PrintWriter construction method can specify parameters, realize automatic refresh cache (AutoFlush);

5. The PrintWriter method is more widely constructed.

-------------------------------------------------------------------

PrintWriter and BufferedWriter are inherited java.io.Writer, so many functions are the same. However, PrintWriter provides a println () method to write line breaks for different platforms, and BufferedWriter can set any buffer size.
OutputStream can be passed directly to PrintWriter (BufferedWriter cannot receive), such as:
PrintWriter out
   = new PrintWriter (new Bufferedoutputstream) (New FileOutputStream ("Foo.out"));
or use OutputStreamWriter to convert OutputStream to Wrtier. Then you can use the BufferedWriter. The
API documents are well written.
