Hehehe... berikut ini saya terbitkan kode sumber alias source code program kalkukatrok ups! kalkulator GUI menggunakan AWT. Kenapa AWT lagi? yaaahhhhh suka-suka gue laahhhh. Yang perlu digarisbawahi : ini program bener-bener katrok... kalo masih ada bug-nya... yaaa harap dimaafkeun... namanya juga katrok! hehehe
Kali ini program menggunakan WindowListener dalam bentuk anonymous inner class untuk menyingkat penulisan source code (bandingkan dengan program kalkulator GUI Java AWT culun [lihat] yang masih meng-implements WindowListener)
Oh iya, kalo nemu bug-nya dan bisa membuang bug-nya, bagi-bagi ya! ciao!
