Bufferedreader Class Example

/*

Bufferedreader improves performance by buffering input. It has two constructor functions: bufferedreader (Reader inputstream) bufferedreader (Reader inputstream, int bufsize). The first method is to create a buffer stream with the default buffer length. Second, the buffer length is input by bufsize. Similar to throttling, buffering an input primary stream also provides the basis for supporting reverse movement in the available buffer. To support this, bufferedreader implements the mark () and reset () methods, and bufferedreader. marksupported () returns true ..
