Thread: [Method] Help ?

Hey first time poster, first year of computer programming so I thought to myself, why not sign up for a forum ! So here I am ahah.

Anyways I'm a bit stumped on my assignment, and would like a bit of clarification, I'll show you what I've got so far.

Basically it's the old Jelly Bean game, ask users how many will be playing, and then they enter their names, their guesses and so on.

Here's my code so far.

import java.util.Scanner;
 
public class M_H_Project2JellyBeans
{
 
	public static void main(String[] args)
	{
		Scanner input = new Scanner(System.in);
 
 
			 //introduce the program to the user 
		System.out.print	( "\t    Welcome to Moe's Jelly Bean Guessing Game! " + 
											  "\n\t    ******************************************" + 
											  "\n   Can you guess correctly how many Jelly Beans are in the jar ? " + 
											  " \n  -The number of Jelly Beans in the jar ranges from 1001 to 1999- " );
 
			//ask how many people will be making a guess
		System.out.print( "\n\n How many people will be attempting to guess the right number today ? " );
		int arraySize = input.nextInt();
 
			//create a String array for the names and an int array for the guess 
		String[] nameArray = new String[arraySize];
		int[] guessArray = new int[arraySize];
		int xNumber;
			      //create random jelly bean number
		int jellyBeans =(int)(Math.random()*(1999-1001+1) + 1001);
 
 
 
		        //set up a for loop to enter the data
		for(int i = 0; i < nameArray.length; i++)
		{
 
			input.nextLine();		//clear the buffer
 
			      //ask for name of person
 
			System.out.print("Enter name of person #" + (i+1)+ ":");
			nameArray[i] = input.nextLine();
 
				   //do-while loop
			do
       {
           //Ask the user to enter their guess.
				   System.out.print(nameArray[i] + ", Enter your guess between 1000 and 2000: ");
           guessArray[i] = input.nextInt();
 
           //Let user know they've entered an invalid number if number they've entered
           //does not range from 1001 to 1999 !
           if ( guessArray[i] <= 1000 || guessArray[i] >= 2000 )
           {
          	 System.out.println("Don't be silly ! Your guess has to be between 1001 to 1999...Please try again.");
           }
 
       } while(guessArray[i] <= 1000 || guessArray[i] >=2000);  
 
 
			 {
      	 System.out.println("\t\t\t\t[*" + nameArray[i] + " has entered '" + guessArray[i] + "' as a guess*]" );
       }
 
 
				if ( guessArray[i] == jellyBeans)
	      { 
	              System.out.println("TheThe winner is" + nameArray + "with a guess of " + jellyBeans 
	                + ", which is exactly the same as the number of jelly beans in the jar."); 
	      }
 
		}
		 System.out.println("\nThere were " + jellyBeans + " Jelly beans in the jar");
 
       int lowestDifference = findLowestDifferencehelper.findLowestDifference(jellyBeans, guessArray[0]);
 
 
       System.out.println( "Your guess was " + lowestDifference + " jelly beans away from the actual number.");
 
 
 
 
 
 
 
      }
 
}

And here's the method i've created to findLowestDifference() of the users guess and the actual randomized amount of jellybeans.

public class findLowestDifferencehelper
{
 
	/*
	 *MethodName: findLowestDifference()
	 *Purpose: determines the difference between actual Jellybeans and players' guess
	 *Accepts: an array of type int
	 *Returns: the difference
	 */
	public static  int  findLowestDifference(int num1, int num2)
	{
		int lowestDifference =  Math.abs(num1 - num2);
 
		return lowestDifference;

Now my problem is, when i run the program, and enter let's say 2 users, and enter their guesses, i only get a difference for the first user.

 

	    Welcome to Moe's Jelly Bean Guessing Game! 

	    ******************************************

   Can you guess correctly how many Jelly Beans are in the jar ?  

  -The number of Jelly Beans in the jar ranges from 1001 to 1999- 



 How many people will be attempting to guess the right number today ? 3

Enter name of person #1:Moe

Moe, Enter your guess between 1000 and 2000: 1300

				[*Moe has entered '1300' as a guess*]

Enter name of person #2:Jon

Jon, Enter your guess between 1000 and 2000: 1500

				[*Jon has entered '1500' as a guess*]

Enter name of person #3:Steve

Steve, Enter your guess between 1000 and 2000: 1800

				[*Steve has entered '1800' as a guess*]



There were 1008 Jelly beans in the jar

Your guess was 292 jelly beans away from the actual number.

I need to create a reportWinner() method, however, how do i make my code give me the lowestdifference for each and every guess ?




This is what the program is supposed to look like when run when i finish.

 

How many players will be making guesses today? 3

Please enter name # 1: Mike

Mike, enter your guess between 1000 and 2000: 1585

Please enter name # 2: Bill

Bill, enter your guess between 1000 and 2000: 1376

Please enter name # 3: Tony

Tony, enter your guess between 1000 and 2000: 1723



There were 1139 jelly beans in the jar.



The winner is Bill with a guess of 1376, which is 237 away from the actual number of jelly beans.

Thanks in advance guys, I hope I didn't post too much at once ahah.

You're only checking against the first user:

int lowestDifference = findLowestDifferencehelper.findLowestDifference(jellyBeans, guessArray[0]);

Hmm okay i see , how would I check against all users ?

Someone just help real quick please

Alright I think I get it, thanks a lot !

That's pretty rude, and you're lucky somebody felt like helping you this time. For the future, I'd recommend you show us what you think the answer is, preferably in SSCCE form, when asking a question like that. Show some effort.

Are you joking ?

Did you even read my code ? How much effort did I put in ? You act like i came here expecting someone to do my homework for me, I wrote my method and everything, all I asked for was how would I make it possible to evaluate all guesses. I didn't even ask for code... aussiemcgr was just nice enough to show me, I had a clue that i needed a loop.

Thanks for your help though, i'm rude eh ?

Excellent. I did read your code. In fact, I pointed out exactly what you were doing wrong.

You could have said something like, "oh, I see my error now, and I think maybe if I did XYZ, I could fix my problem. But when I tried that, ABC happened instead. Here is some code that demonstrates where I'm stuck."

Instead, you took the lazy way out, without showing any effort or even enough effort to use basic punctuation. You're lucky you received the help you did.
