Java-preliminary understanding of-I/O stream (character stream-buffer-bufferwriter)

One.

For buffers, also classified, buffered read and buffered write. Now explain the buffer write.

Why there are bufferwriter such objects exist, that is, the previous ch,buf and other things and flow objects together, so that they become a whole.

By incorporating the buffered functionality, the stream object is really an efficient object class.

Strangely, there is no buffer used to write the writer character stream object here. Does it say that buffers are available?

Use the Buffer object after the following syntax:

After reading the program, it is not the same as the buffer object I understand. I thought it was a buffer stream object, not a buffer object, and the stream object added the buffered functionality.

The buffer is actually encapsulated as an object, no longer a simple variable or array, but an object class.
