Java ve Animasyon
Java'da animasyon yapmak isteyen arkadaşlara yardımcı olması ümidiyle böyle bir ders hazırlamak istedim.
Java ile çalışmak isteyen arkadaşlara Merhaba...
Aşağıda çalıştıracağınız java kodumuzla GKA(grafiksel kullanıcı arayüzü) çizip, fareyle birlikte, dikdörtgen ve kare çizebiliyoruz, her saniyede.
Aynı zamanda renk değiştiren kodumuzla birlikte, şekillerimzin renkleri de değişmektedir.
Kolay gelsin
