Making a loop and creating variables based off of user input

[seanfmglobal]

Ok I'm just wondering how I would right a piece of code that will take user input and based off the integer entered knows how many variables to store. I sorta got stuck when reading my code and realized that all the variables would get stored in the same place and erased the previous int. Here's what I have....

public class AgeTest {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
	
		Scanner input = new Scanner;
		
		int age;				// The age that was entered by user
		int control = 0;		// The control variable
		int amountusr;			// The amount of users at the time that will be entering ages
		
		System.out.println("Hello, how many users will be entering ages today?\n"); // Output this text
		amountusr = input.nextInt()
		
		amountusr = control;
		
		int first;
		int second;
		int third;
		int fourth;
		int fifth;
		int sixth;
		int seventh;
		int eight;
		int ninth;
		int tenth;
		
		while (control != 0)	{
			System.out.println("What is your age?\n");
			first = input.nextInt()
			control--;
			
		}

	}

}

I know this code is not the best and it isn't finished but I'm working on it and I have a test for my CS class and I would like to figure this one out so I can continue. Thanks everyone.

create an int[] and make it have size input.nextInt().

Then loop through that array, for each i, prompt user to enter there age and add that input to position i in the array

Yes as sunde887 said use an array.

Arrays are very fun :) and would be perfect for what you are asking.

So a user inputs 10 for "amount of users". Now amountusr = 10. Now you can immediately create an array called users (or whatever name). And in java you need to declare an array like this.

int[] users;

When you find out the amount of users you can add it like this.

users = new int[amountusr];
//or
users = new int[19];

or the same thing.

int[] users = new int[amountusr];

You can store integers to this array like this

users[0] = 35;
users[1] = 25;
users[2] = 52;
users[3] = 16;

so this is really cool when you use loops with them and this is what you are needing to do.

I would try a for loop where your while loop is. You will need the array length and you can get an array length like this.

users.length;

You will need to start at 0 so have your for loop go from 0 to user.length.

if "i" is your for loop integer variable name then it might look like this.

for (int i = 0; i < users.length; i++) {
     users[i] = input.nextInt();
}
