How can I use the BufferedReader to take the input for developing a console-based Java application?

In the context of Java programming language, if you need to use the BufferedReader for the development of a Console-based Java application then you can use the InputStreamReader and BufferedReader classes for this particular objective. Here is the example given of how you can get this particular target:-

Import java.io.BufferedReader;

Import java.io.IOException;

Import java.io.InputStreamReader;

Public class UserInputExample {

    Public static void main(String[] args) {

        // Create BufferedReader object to read input from the console

        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

        Try {

            // Prompt the user for input            System.out.print(“Enter something: “);

            // Read user input

            String userInput = reader.readLine();

            // Process the user input as needed

            System.out.println(“You entered: “ + userInput);

        } catch (IOException e) {

            // Handle IOException if it occurs

            e.printStackTrace();

        } finally {

            Try {

                // Close the BufferedReader

                Reader.close();

            } catch (IOException e) {

                // Handle IOException if closing fails

                e.printStackTrace();

            }

        }

    }

}

Here are the some considerations give which should be kept in mind during going through with the above process:-

Exception handling

Try to handle Input-output exceptions for managing potential input or output errors.

Resource Cleanup

You can use the “finally” block to close the BufferedReader so that you can avoid resource leaks.

Input validation

Try to consider validation and processing user input according to your particular application so that it can meet the expected or required criteria.
