mcm mne nk wt ea??hope phm

sori. takleh tolong banyak. takde compiler..

try getch.....

so menu keluar dulu. bile user nak masukkan menu dia akan tekan enter baru input keluar. takpun buat satu modul timer. object oriented.

sajeje,,
xd la,,
nak nmpak coding tu lg bst..
hehe,,
ha,taw x mcm mane nk bg no yg ad perpuluhan tu jadi pendek skit,,
contoh : 12.56794736365373
nak jdikan mcm ni : 12.568

code kt mna yg nk nmpk lg best tu..hehe
cuba ganti double tu dgn float

guna BigDecimal class

//round up kepada 2 decimal

        BigDecimal big = new BigDecimal(amount);
        big = big.setScale(2, BigDecimal.ROUND_HALF_UP);
        amount = big.doubleValue();
        System.out.println(amount);

just change the value kat big = big.setScale(3, BigDecimal.ROUND_HALF_UP); untuk bust 3 decimal places
