For Loop Examples:

import java.util.*;

/**

* This program demonstrates a for loop.

*/

public class ForLoop

{

public static void main(String[] args)

{

Scanner in = new Scanner(System.in);

System.out.print("How many numbers do you need to draw? ");

int k = in.nextInt();

System.out.print("What is the highest number you can draw? ");

int n = in.nextInt();

/*

* compute binomial coefficient n*(n-1)*(n-2)*...*(n-k+1)/(1*2*3*...*k)

*/

int lotteryOdds = 1;

for (int i = 1; i <= k; i++)

lotteryOdds = lotteryOdds * (n - i + 1) / i;

System.out.println("Your odds are 1 in " + lotteryOdds + ". Good luck!");

}
