Contoh Game Sederhana Dengan JAVA ( Game kumbang memakan ulat )

Game kumbang memakan ulat          

      Kali ini saya akan memberikan contoh tentang sebuah game java sederhana yang pernah saya buat dan ini merupakan game pertama yang saya buat dengan menggunakan bahasa pemograman Java. Mungkin bagi temen - temen yang ingin mengembangkan game saya ini menjadi lebih baik lagi silakan saja.

Logika game ini adalah :

• Player dengan karakter kecoa (Kecoa ato kumbang saya juga gak tau mas bro mbak bro....hehehehehe  :D ) harus memakan ulat yang berwarna hijau sebanyak mungkin untuk mendapatkan POINT sebanyak-banyaknya.
• Player harus menghindari musuh supaya terhindar dari kematian :D
• Game ini terdiri dari 3 class yaitu class Game, musuh, dan Makanan.

Berikut Script java nya boos :
