Postingan kali ini masih membahas mengenai grafika komputer dalam bahasa java, sub bab kali ini penulis akan membahas animasi dasar dala grafika komputer.
Bila kita akan membuat animasi dalam java pasti memerlukan yang namanya Thread, nah di dalam Thread, method yang paling penting adalah run() karena dalam method inilah semua tugas animasi akan dijalankan. sebelum menjalankan method run kita harus memanggil terlebih dahulu yang namanya start().
Untuk mengatur perilaku Thread anda memerlukan sleep() disini anda bisa mengatur kecepatan pergerakan object dan lain lain.. untuk contoh animasi sederhana berikut source codenya

ntar hasilnya kurang lebih seperti ini
