Mau bagi2 Knowledge Java Console part 2

cara membuat segitiga dan jajargenjang di java



ini adalah Ujian test aslab di BINUS dalam waktu 20 menit T.T
sayang sekali g kagak bisa kerjain soal beginian dalam waktu 20 menit

g kerjain di rumah sih dalam waktu 2 jam huffff lama sekali ...

nih g share Codingannya semoga membantu ^^

SEMOGA MEMBANTU KALIAN LAGI...
yah kalo kurang bisa ,
bisa di tanya2 kok di message box kalo g OL ^^
