can anyone say in simple language what valueOf()function does

Guys to all those who have got a confusion in static variables and non-static(instance variables ) i found an interesting example which will easily make you understand the difference.....plz see to it patiently....Worthy...
NON-STATIC Variables (Instance variables) : These variables' values are unique to each object of a class 
Example : the currentSpeed of one BICYCLE is different from the currentSpeed of another
STATIC Variables ( Class variables ) : There is exactly one copy of these variables in existence no matter how many objects have been created for a single class.....
Example : No.of Gears for a particular Bicycle can be marked as static since the same number of gears will apply to any other bicycle too ..( here bicycle refers to objects ...that means no matter what object it might be the value of static variable remains same) ...Keyword final can be attached to them if you want the variable's value to be constant througout....
