Trouble with While Statement

[Chad.Curtiss]

I need to make a section of code re- run depending on user input. I tried using a while loop but I could not get it working!

import java.util.Scanner;
import java.util.Random;
public class Game {
    public static void main(String args[]){
        System.out.println("Welcome to the Gumball Guessing Game");
        System.out.println("Please enter your first Guess!");
        Scanner input = new Scanner(System.in);
        Random gumballs = new Random();
        int number;
        int gum;
        
        for(int counter=1; counter<=1;counter++){
            gum = gumballs.nextInt(5);
            number = input.nextInt();
       
        
        if(number == gum){
            System.out.println("CORRECT!!! You won!");
            }
        }
    }

Your for loop only runs its body once (counter > 1 on the second pass); is that what your problem is about?

kind regards,

ps. fix your indentation.

Yeah, the problem here seems to be that there isn't a while statement.

Hi,

How about trying to make a while statement then?

while(number != gum)

That's the route i'd be going down here.

[Chad.Curtiss]

well I tryed to fix it with a while loop again but to no avail. Sorry if I seem really dumb... just new to Java!


Java code:
import java.util.Scanner;
import java.util.Random;
public class Game {
public static void main(String args[]){
System.out.println("Welcome to the Gumball Guessing Game");
System.out.println("Please enter your first Guess!");
Scanner input = new Scanner(System.in);
Random gumballs = new Random();
int number;
int gum;
while(number <||> gum){

for(int counter=2; counter<=5;counter++){
gum = gumballs.nextInt(5);
number = input.nextInt();
}
}
if(number == gum){
System.out.println("CORRECT!!! You won!");
}else{
System.out.println("WRONG");
}

}
}

What is that '<||>' thing?

kind regards,

Jos

[Chad.Curtiss]

greater than or less than.

[awinston]

<||> is not a valid boolean operator in Java, I'm afraid. The most convenient way to do an equivalent test that I know of is:

 (number < gum || number > gum)

Or you could just do this, right?

(number != gum)

[Chad.Curtiss]

I did it like you said and it now says that the variables gum and number may not have been initialized?

Discard my previous reply I have gotten it working... I just had to put the while loop in a slightly different spot. Thanks for all of your help. And for tolerating my Java ignorance. lol
