CharArrayReader Class ready() method

  • ready() method is available in java.io package.
  • ready() method is used to check whether this stream is ready to be read or not and as we know that this stream is ready by default.
  • 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 stream status.
    IOException: This exception may throw while getting any input/ output error.


    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 
// CharArrayReader

import java.io.*;

public class ReadyOfCAR {
 public static void main(String[] args) {

  CharArrayReader car_stm = null;
  char[] c_arr = {

  try {
   // Instantiates CharArrayReader
   car_stm = new CharArrayReader(c_arr);

   // By using ready() method isto 
   // check whether this stream support is
   // ready to be read or not
   boolean status = car_stm.ready();
   System.out.println("car_stm.ready(): " + status);

  } catch (Exception ex) {
   System.out.print("Stream Not Ready To Be Read!!!!");
  } finally {

   // Free all system resources linked
   // with the stream after closing
   // the stream

   if (car_stm != null)


car_stm.ready(): true
