BufferedReader Class ready() method

  • ready() method is available in java.io package.
  • ready() method is used to check whether this BufferedReader stream is ready or not to be read.
  • ready() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • ready() method may throw an exception at the time of checking the status of the stream.


    public boolean ready();


  • It does not accept any parameter.

Return value:

The return type of the method is boolean, it returns true when this stream is ready to be read otherwise it returns false.


// Java program to demonstrate the example 
// of boolean ready() method of 
// BufferedReader

import java.io.*;

public class ReadyBR {
    public static void main(String[] args) throws Exception {
        // To open text file by using 
        // FileInputStream
        FileInputStream fis = new FileInputStream("e:/includehelp.txt");

        // Instantiates InputStreamReader 
        InputStreamReader inp_r = new InputStreamReader(fis);

        // Instantiates BufferedReader 
        BufferedReader buff_r = new BufferedReader(inp_r);

        // To check whether this stream
        // buff_r is ready to be read or not
        boolean status = buff_r.ready();
        System.out.println("buff_r.ready(): " + status);

        // To check whether this stream
        // inp_r is ready to be read or not
        status = inp_r.ready();
        System.out.println("inp_r.ready(): " + status);



buff_r.ready(): true
inp_r.ready(): true
