See if this makes Sense
"Parsing Primitives is Valueable in Wrapper class.
Remember all are STrong NFE and Radix are not in FDs!!"
Means ParseXXX method returns Primitive type
ValueofXXX returns wrapper class.
STR stands for Static, String
All methods are staic, take string as a parameter, and throw NFE i.e. NumberFormatException.
Both methods of FDs means Float and Doubles classes do not take radix as a argument.
Anybody can change this to make more redable and memorizable
