// File   : editor/NutPad.java -- A very simple text editor
// Purpose: Illustrates use of AbstractActions for menus.
//          It only uses a few Action features. Many more are available.
//          This program uses the obscure "read" and "write"
//               text component methods.

perlu di perhatikan,, ini bukan murni buatan saya lho,, yang berwarna merah itu adalah nama pembuatnya mungkin yah,, saya cuma share aja supaya bagi rekan rekan yang bosan dengan hello word dan ingin mencari tahu yang lain bisa memanfaatkannya juga,, dan satu hal yang harus di perhatikan lagi,jika ingin mengubah kelas dan nama notepad ini, coba lihat bagian yang berwarna orange sebelumnya bernama nutpad, jangan sampai salah,,
dan godaipad ini saya buat dengan menggunakan blueJ,,
semoga bermanfaat..
pada posting berikutnya ada skrip untuk membuat jam digital java,, hehehe...
