import java.io.*;

public class ClearErrorOfPW extends PrintWriter {
    public ClearErrorOfPW(OutputStream os) {
        super(os);
    }

    public static void main(String[] args) {
        String str = "Java Programming";

        // Instantiates ClearErrorOfPW
        ClearErrorOfPW p_stm = new ClearErrorOfPW(System.out);

        // Display str
        p_stm.println("str: " + str);

        // By using flush() method is to
        // flush the stream immediately
        p_stm.flush();
        System.out.println("Stream Flushed...");

        // By using clearError() method is used to
        // clear internal error state
        p_stm.clearError();

        // By using close() method is to 
        // close the stream p_stm
        System.out.println("Stream Shutdown....");
        p_stm.close();
    }
