In how many ways can a user take input in Java?

- The read methods are not synchronized.
What is InputStreamReader and BufferedReader in Java?
BufferedReader reads a couple of characters from the input stream and stores them in a buffer. The InputStreamReader reads only one character from the input stream and the remaining characters still remain in the streams, so there is no buffer in this case.
