        // The string to be written in the Writer
        String str = "GeeksForGeeks";
  
        try {
  
            // Create a PrintWriter instance
            GFG writer
                = new GFG(System.out);
  
            // Write the above string to this writer
            // This will put the string in the stream
            // till it is printed on the console
            writer.write(str);
  
            // Now clear the stream
            // using clearError() method
            writer.clearError();
  
            System.out.println("\nHas any error occurred: "
