can anyone tell me what is the difference between read() and readline();?

Question

package com.learn.java;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class BufferReaderInput {

    public static void main(String[] args) throws IOException {
        BufferedReader bufferreaderIn = new BufferedReader(
                new InputStreamReader(System.in));
        System.out.println("Enter your Name");
        String Name = bufferreaderIn.readLine();

        System.out.println("Enter your age");
        int age = Integer.parseInt(bufferreaderIn.readLine());

        System.out.println("Enter your salary");
        int sal = bufferreaderIn.read();

        System.out.println("Hi, I'm " + Name + " my age is " + age
                + " and my salary is " + sal);
    }

}

When I enter salary using obj.read(); it is not giving the right output.

With that can anyone tell me what is the difference between read() and readline()?

Answer 1

As from the documentation of BufferedReader, we have this for read:

Reads a single character.

And this for readLine:

Reads a line of text. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed.

So, set apart the details of when a line is considered to be terminated, the difference is that the first one read a single character whilst the second one read a whole line.
