expression evaluator

i am trying to create an expression evaluator in java which takes input from a

text file or a user input screen and compare the values with the attributes of an

object in memory thus returning a boolean indicating whether or not the critaria

is satisfied or not .the problem i am facing is to get the name of the field .i

am assuming that the class which will be evaluated with this program have a function

to return the value of the desired field but facing a problem of getting the field

name .please suggest some readings and sites to provide me some info about this

topic

thank you

if it is just getting the field name, you can do that using

reflection mechanism.


java.lang.Class has the apis to get the fields, constructors and methods

in a particular object.
