This is similar to Scanner in=new Scanner (system.in)
Constructs a character stream cache that contains characters converted into bytes that are stored in the console input.

Here, with the sentence. Add a stream of characters to the buffered stream
In fact, the above two sentences can be divided into three sentences or a sentence

* InputStream is = system.in;
InputStreamReader ISR = new InputStreamReader (IS);
BufferedReader bufr = new BufferedReader (ISR);
or a sentence
BufferedReader br=new BufferedReader (New InputStreamReader (system.in)); This is good.
