simulation buy fuel with specifications:
Input form:
money / how many liters that will be purchased
Type of fuel to be purchased
Indicators will continue (increasing 0.1liter) for the total price / number of liters of fuel purchased not exceed demand
Output states:
The number of liters purchased (if the input in the form of money)
Total money to be paid (if the input in the form liter)

program java menghitung nilai faktorial

Award as the value of factorial is the result of the multiplication of positive integers less than or equal to the value N. Writing is usually a factorial: n!

berikut programnya :

import jeliot.io.*;


public class faktorial
{
public static void main (String[ ] args)
{
long limit = 20; // menghitung faktorial integer daeri 1 – 20
long faktorial = 1; // pendefinisian variabel faktorial

for (int i = 0; i <= limit; i++)
{
faktorial = 1;

for (int faktor = 2; faktor <= i; faktor ++)
faktorial *= faktor;
System.out.println (i + "!" + " adalah " + faktorial);
}
}
}
