Check uppercase or lowercase letter

Hi guys!;) Is there a way so i can find if a string starts with an uppercase letter or a lowercase letter? For example : String temp = "Hello" can i find if it starts with an uppercase or a lowercase:confused: .i have a program in which i save variables(i read them from a txt ex math x,y,z) in a vector as Strings with the first letter(first char) lowercase and i save the stables(ex George, Human ) as Strings with a first letter uppercase.after i save the Stables and the variables(they are all mixed up in the txt)in a vector can i separate them by checking the first letter(by using a method?)?? in order to find if a String is Stable or if a String is variable:rolleyes:. thanks!!:D

ok problem solved!! i found someone's else thread with a similar problem.

with this method i solved my problem. Thanks guys!!

public boolean isStable(String word)
{
char[] charArray;
charArray = word.toCharArray();
if (Character.isUpperCase(charArray[0]))
return true;
else
return false;
}
