BufferedReader Class close() method

  • close() method is available in java.util package.
  • close() method is used to close this BufferedReader stream and free all other system resources linked with this stream.
  • close() 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.
  • close() method may throw an exception at the time of the closing stream.
    IOException: This exception may throw while performing input/output operation.

Syntax:

    public void close();

Parameter(s):

  • It does not accept any parameter.

Return value:

The return type of the method is void, it returns nothing.

Example:

// Java program to demonstrate the example 
// of void close() method of BufferedReader

import java.io.*;

public class CloseBR {
    public static void main(String[] args) {
        try {
            // 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);

            // Close the stream and free
            // system resources linked with 
            // this stream buff_r
            buff_r.close();
            inp_r.close();
            fis.close();

            // we can't perform read() on
            // buff_r because this stream is 
            // already closed
            buff_r.read();
        } catch (Exception ex) {
            System.out.println("buff_r: " + ex.toString());
        }
    }
}

Output

buff_r: java.io.IOException: Stream closed
