 // Tipe pertama: Gunakan filereader dan fileWrite untuk membaca satu karakter pada waktu filereader fr = filereader baru ("d: //a.txt"); fileWriter fw = fileWriter baru ("d: //b.txt"); int ch; while ((ch = fr.read ())! = {fw.write (ch);} fw.close (); fr.close ();

 // The second type: Use FileReader and FileWrite to read one character array at a time FileReader fr = new FileReader("D://a.txt");FileWriter fw = new FileWriter("D://b.txt");char[] chs = new char[1024];int len;while((len = fr.read(chs)) != -1) {fw.write (chs, 0, len);} fw.close (); fr.close ();

 // Tipe ketiga: Gunakan FileOutputStream dan FileInputStream, baca satu byte pada waktu fileInputStream fis = fileInputStream baru ("d: //a.txt"); fileOutputStream fos = FileOutputStream baru ("D: //B.TXT"); int ch; while ((che = fis. {fos.write (ch);} fos.close (); fis.close ();
