Beginner Java Code not working - While loop error

I have an error in the while loop. The While Statement is showing as an error in Eclipse? What am I missing... (Yes I know it is simple code... I am going to start with beginner code first.

/**

*/
public class DietCokeSong { 
/**
 * @param args
 */
public static void main(String[] args) {
    int dietCokeNum = 99;
    String word = "Cans of Diet Coke";
    While(dietCokeNum > 0) {

        System.out.println(dietCokeNum + " " + word + " on the wall");
        System.out.println(dietCokeNum + " " + word + ".");
        System.out.println("Take one down.");
        System.out.println("Pass it around.");

     开发者_如何学Python   dietCokeNum = dietCokeNum - 1;

        if(dietCokeNum > 0) {
            System.out.println(dietCokeNum + " " + word + " on the wall");
        } else {
            System.out.println("No more Cans of Diet Coke on the wall.");
        }
    }
}
}

The W in "while" should not be capitalized. I think that is all.

while should be in lower case.... and "diet coke" should be "beer"...
