Please Help

Hi all ,

I am having some difficulties to run the below program and willing for some help..

-Create a method called countSixes in which you roll a die 100 times and count the number of sixes that result. The method should return (not output) the result. So if you invoke countSixes() and out of the 100 times, there were 23 sixes, your method should return 23.

here's what i did so far !!



public class Titel1

{
public static void main(String[] args)
{

// Create one dice, each with 6 sides



public static int countSixes()
{
int die1 = new Die(6);

countSixes = 0;

for ( int i = 0 ; 100>i ;i++)
{
die1.roll();

if (die1.conutSixes()== 6)



return countSixes;


}

}

For starters read the API documentation for the Random class. Play special attention to the nextInt( ... ) method.

kind regards,

I have read the random class but it's still not make sense to me !!

I would also suggest you study some basic material on the structure of a valid Java program. At the moment you are attempting to declare the countSixes() method within the main() method which isn't valid. Also the number of braces don't add up: they should come in matching pairs of { and }.

Model the general program structure on the simplest examples you will have read about. And compile often, fixing the errors that the compiler tells you about as they arise.

If you can't understand the compiler messages then do post back with your code and the message. Or, later, if you have some specific question about the API documentation of a method, ask that. But, as I'm sure you realise, no-one is actually going to write the code for you. (Or at least I hope they won't as that would deprive you of all the fun!)

I have reedited my codes and i just got an error message i didn't understand it ,, also I am just wondering if i am so far so good with this progress


public class Titel1

{
public static void main(String[] args)
{
countSixes();

}

// Create one dice, each with 6 sides



public static int countSixes()
{
die1 = new Die(6);

countSixes = 0;

for (int i=0;i<100;i++)
{

return countSixes;


}

}


------------------------ here's the error i didn't understand !!

C:\Users\Alex\Desktop\Titel1.java:29: reached end of file while parsing
}
^
1 error

Tool completed with exit code 1

When you post code the thing is to put [code] at the start and [/code] at the end. That way it appears like this:

public class Titel1

{
	public static void main(String[] args)
	{
		countSixes();

	}

	// Create one dice, each with 6 sides



       public static int countSixes()
       {
		    die1 = new Die(6);

            countSixes = 0;

       for (int i=0;i<100;i++)
       {

		return countSixes;


}

}

The error means that the braces don't match up. The compiler reaches the end of the file while still looking for a }.

Don't just add a } randomly. Think about which { goes with which } and have them line up in your source code.

Did you read what the compiler had to say? It was happily parsing your source code while all of a sudden there was no more input while the compiler expected some more. Count your curly brackets and see for yourself.

How you create the die item is also incorrect. The correct way is to create a reference, then create the object, then link them with =

Object o = new Object();

Whats your die class look like? Using a Random object would probably be much simpler

Random rand = new Random();

is the way it should look to create a random object. I'll leave the rest of the stuff required for random up to you.
