BufferedReader vs Scanner in Java Here is the 5 key differences between the Scanner and BufferedReader class of Java API: 1. Scanner is a much more powerful utility than BufferedReader. It can parse the user input and read int, short, byte, float, long and double apart from String. On the other hand BufferedReader can only read String in Java . 2.

BufferedReader is older than Scanner. It's present in Java from JDK 1.1 onward but Scanner is only introduced in JDK 1.5 release. 4. Scanner uses regular expression to read and parse text input. It can accept custom delimiter and parse text into primitive data type e.g. int, long, short, float or double using nextInt() , nextLong() , nextShort() , nextFloat(...
