Thread: Scanner

hello,
I need to create a Scanner in my code, and I've googled it and it seems like I can open the Scanner utility just fine. But I found out later that you need to close the Scanner, and I can't seem to figure that out. I think the basic setup is --

import java.util.Scanner;

body of code

Scanner keyboard = new Scanner(System.in);
int productnumber = keyboard.nextInt();

then more code

scanner.close();

The thing is, scanner.close(); never works in Eclipse. It always complains with the error " scanner cannot be resolved" like it thinks scanner is a variable.
I think because I'm not closing the scanner the code doesn't run correctly.
Anybody have any ideas?

thank you so much for the reply Jim, but
keyboard.close()
or
keyboard.close();
both give the "keyboard cannot be resolved" error.

okay, actually, I decided to start over, but the Scanner is still my problem. I will include the code, but the bigger problem for me right now is the the integer that I think should be holding me keyboard input isn't keeping the value entered.
So, this is what I have so far
this is my main
[code]
public class Sales{

public static void main(String[] args) {

SalesTest productNumberObject = new SalesTest();
productNumberObject.askProductNumber();

SalesTest resultsObject = new SalesTest();
resultsObject.showResults();

}
}
[\code]

and this is my constructor

[code]
import java.util.Scanner;

public class SalesTest {

int getProdNumb;

public void askProductNumber() {

Scanner input = new Scanner(System.in);
System.out.print("Please enter the product number (1 - 5) (0 to stop): ");
int getProdNumb = input.nextInt();
}

public void showResults() {

System.out.print(getProdNumb);
}

}
[\code]

Thank you!! that did it!
only one more thing if you don't mind.
I need my System.out.println statements to be formatted to only have 2 decimal places.
right now they look like this
System.out.println("Product 1: " + dollarvalueprod1);
I keep seeing to use
System.out.printf("%.2f", val);
but it doesn't work if I do something like
System.out.println("Product 1: %.2f" + dollarvalueprod1);
or
System.out.println("Product 1: + "%.2f" dollarvalueprod1);

Thanks again, I wasn't sure about the printf thing, but after some googling I came up with this.
System.out.print("Product 1: ");
System.out.printf("%.2f",dollarsmadeprod1);
System.out.println("");
System.out.print("Product 2: ");
System.out.printf("%.2f",dollarsmadeprod2);
System.out.println("");

Not sure if it's the most elegant code, but it got the job done! Thank you so much for all your help!!
