2 things to point out. A for loop is used when the the number of iterations is fixed. If the number of iterations is not fixed then use the while loop and the 2 things is a while loop will execute the code block at least one time before checking if the condition is true.

Doesn't work for me for some reason...

public class LoopsApp {
public static void main(String[] args) {
char letter = "A";

while (letter <= "Z")
{
System.out.println("The letter is: " + letter);
letter++;
}
}
}
