PipedOutputStream Class close() method

  • close() method is available in java.io package.
  • close() method is used to close this PipedOutputStream and free all 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 closing the stream.
    IOException: This exception may throw when getting any input/output error while performing.

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 PipedOutputStream

import java.io.*;

public class CloseOfPOS {
    public static void main(String[] args) throws Exception {
        int val = 65;
        
        try {
            // Instantiates PipedInputStream and 
            // PipedOutputStream
            PipedInputStream pipe_in = new PipedInputStream();
            PipedOutputStream pipe_out = new PipedOutputStream();

            // By using close() method is to close
            // the stream
            pipe_in.close();
            pipe_out.close();

            // when we call write() method after closing the
            // stream will result an exception
            for (int i = 0; i < 3; ++i) {
                // By using write() method is to
                // write the val to the stream pipe_out
                pipe_out.write(val);
                val++;
            }
        } catch (Exception ex) {
            System.out.println("Stream Closed Before!!!!");
        }
    }
}

Output

Stream Closed Before!!!!
