In Java, there are three distinct ways for perusing contribution from the client in the order line environment(console).
1.Using Buffered Reader Class
This is the Java old style technique to take input, Introduced in JDK1.0. This technique is utilized by wrapping the System.in (standard info stream) in an InputStreamReader which is enclosed by a BufferedReader, we can peruse contribution from the client in the order line.
- The input is buffered for efficient reading.
- The wrapping code is hard to remember.
Note: To read other types, we use functions like Integer.parseInt(), Double.parseDouble(). To read multiple values, we use split().
2. Using Scanner Class
This is likely the most favored technique to take input. The fundamental motivation behind the Scanner class is to parse crude sorts and strings utilizing ordinary articulations, anyway it is likewise can be utilized to peruse contribution from the client in the order line.
- Advantageous techniques for parsing natives (nextInt(), nextFloat(), … ) from the tokenized input.
- Ordinary articulations can be utilized to discover tokens.
- The reading methods are not synchronized

3. Using Console Class
It has been turning into a favored route for perusing client’s contribution from the order line. Furthermore, it very well may be utilized for perusing secret word like contribution without repeating the characters entered by the client; the organization string punctuation can likewise be utilized (like System.out.printf()).
- Perusing secret phrase without repeating the entered characters.
- Perusing strategies are synchronized.
- Configuration string grammar can be utilized.
- Does not work in non-interactive environment (such as in an IDE).
If it’s not too much trouble refer this for all the more quicker methods of understanding information.
