B]I need to do this:[/B]
In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second promt asks the player to choose either High or Low (1 or 2). The player's choice of either High or Low is compared to random number between ! and 13, inclusive. If the number is between 1 and 6, it is considered low (1), if the number is between 8 and 13, it is considered high (2), and 7 is neutral and the player loses points. If the player guessed correctly, the points wagered are doubled and added to the total points. A wrong guess, the player loses the wagered points.


This is what I wrote:

import java.util.*;

public class HiLo
{
public static int oneRound (int choice, int wager, int points)
{
int rand;

rand = (int)(Math.random()*13 - 1);

if (choice == 1 && rand <=6)
{
return (points + wager);
}
else if (choice == 1 && rand ==7)
{
return (points - wager);
}
else if (choice == 1 && rand >= 8)
{
return (points - wager);
}
else if (choice == 2 && rand <= 6)
{
return (points - wager);
}
else if (choice == 2 && rand ==7)
{
return (points - wager);
}
else if (choice == 2 && rand >= 8)
{
return (points + wager);
}
}

public static void main(String[] args)
{
int wager;
int points = 1000;
int choice;

Scanner input = new Scanner(System.in);

System.out.println("Enter a 1 for numbers 1-6, or a 2 for numbers 8-13.");
choice = input.nextInt();

System.out.println("you have 1000 points, enter your wager.");
wager = input.nextInt();

do
{
points = oneRound(choice, wager, points);

System.out.println("You have " + points + " points left.");
}
while (wager < points || wager == 0);
}
}



The problem is that I keep getting a missing return statement

Please help
thank you

Because all of your return statements are in conditionals (the "if"s), there is not a guaranteed return path. Instead of putting the returns in the if clauses, make a variable to hold the calculation and make a single return of that value at the end of the method.
