Read String characters

[MaxGeek]

Hi,
I'm trying to figure out how to read the first character of a String. Like if the user inputs, Yes, YES, y, or No, N.

I'm not sure if its the correct thing to use right now but I'm trying to use "startsWith."

//It is a corrent choice to use startsWith.
//Be careful in using empty string
String hello = "yes";
if (hello.startsWith("yes"))
   System.out.println("Morning");

if (hello.startsWith(""))
   System.out.println("Good Evening");
// you can use charAt for one character but more coding is needed

Could you give me an example of using charAt? I understand that it may be more code, but wouldn't it cover more varieties of input like just Y. Would their be issues with upper case and lower case?

The docs :

http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html

String abc = "Yes";
if (abc.charAt(0) == 'Y' || abc.charAt(0) == 'y') {
 ...
} else {
 ...
}
