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.
Syntax:
public boolean ready();
Parameter(s):
- 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.
Example:
// 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);
fis.close();
inp_r.close();
buff_r.close();
}
}
Output
buff_r.ready(): true
inp_r.ready(): true
