I'm looking to implement something in Java along the lines of:

class Foo{
 private int lorem; //
 private int ipsum;      

 public setAttribute(String attr, int val){
  //sets attribute based on name
 }

 public static void main(String [] args){
  Foo f = new Foo();
  f.setAttribute("lorem",1);
  f.setAttribute("ipsum",2);
 }

 public Foo(){}
}

...where a variable is set based on the variable name without the variable names hard-coded and without using any other data structures. Is this possible?

java reflection eval
