missing return statement...
A single upper case character is supplied to isHex() to return true it is hex 0 - F.
Q1: line public static boolean IsHex(String str) { complains saying "missing return statement", why?
Q2: Is there a better way ofwriting this if statement?
Thank you.

public static boolean IsHex(String str) {
if(str.equals("0") || str.equals("1") || str.equals("2") ||
str.equals("3") || str.equals("4") || str.equals("5") ||
str.equals("6") || str.equals("7") || str.equals("8") ||
str.equals("9") || str.equals("A") || str.equals("B") ||
str.equals("C") || str.equals("D") || str.equals("E") ||
str.equals("F"))

return(str.equals("0") || str.equals("1") || str.equals("2") ||
str.equals("3") || str.equals("4") || str.equals("5") ||
str.equals("6") || str.equals("7") || str.equals("8") ||
str.equals("9") || str.equals("A") || str.equals("B") ||
str.equals("C") || str.equals("D") || str.equals("E") ||
str.equals("F"));
This seems to work. How about simplifying these cmparisions?
