Progam Sederhana Java Swing Konversi Bilangan

Ini adalah contoh program java swing sederhana yaitu kalkulator sebaguna, kalkulator ini bisa anda gunakan untuk konversi bilangan dari desimal ke biner, floating point, ones's complement, two complement dan juga bisa untuk menghintung aritmatika seperti penjumlahan, perkalian, pembagian dan pengurangan. untuk lebih jelasnya langsung

saja ke scriptnya  :
