Java reads and writes files in UTF-8 encoding

The file operation in Java embodies the decorator pattern in design mode. Write to file in Utf-8 encoding:

New FileOutputStream ("test.txt");           New OutputStreamWriter (FOS, "UTF-8");          Osw.write (filecontent);          Osw.flush ();   

To read a file in Utf-8 encoding:

New FileInputStream ("test.txt");      New InputStreamReader (FIS, "UTF-8");      New BufferedReader (ISR);      NULL ;       while NULL ) {         + = line ;          // fill in line break     }
