An application that reads numbers in the range of 0 to 50

[JinFTW]

I'm trying to create an application that reads an arbitrary number of integers that are in the range 0 to 50 and counts how many occurrences of each are entered. At the end of the input processing, I have to print all of the values (including number of occurrences) that were used one or more times.

So far I've set up the scanner, and I had originally thought to use a number of scan.nextInt() in order to calculate each and every one, but I simply can't develop the right counters and link the concepts. Any help would be greatly appreciated!

Post your best effort and ask a specific question about it.

Post your best effort and ask a specific question about it.

This is how far I've gotten, I realize there are a number of mistakes, but I'm currently working on it.


[CODE=Java]import java.util.Scann er;
public class Numbers
{
public static void main (String[] args)
{
Scanner scan = new Scanner (System.in);
final int MAXNUM = 51;
int[] list = new int [MAXNUM];

int current=0;

System.out.prin tln ("Enter a series of numbers between 1 and 50: ");
int number = scan.nextInt();

for (int index = 0; index < 50; index++)
{
list[index]++;



}
for (int index = 0; index < list.length; index++)
{
System.out.prin t ();

}

}
}[/CODE]

Don't forget part B: ask a specific question!

I'm simply wondering how you use an array to give the number of occurrences for each integer that the user enters.

Like what you've done, except after you get the verified input -- call it number, you:

[CODE=Java]list[number]++;[/CODE]
because list[number] records the count of times number was input (not the best name: "list")

Thank you so much! I think I can see where it's going now, much appreciated to you for clearing that up!

Ok after adding list[number]++;
and looking at the problem itself, it appears as though I'm only taking in one value from the user. I hate to bother you guys with this, but I suppose I have another question here, do I need another for loop in this statement? Or am I supposed to use an if-else in order to have this thing read the user's answers again and again?

How else can you execute something repeatedly?
