Reflection - ah, I'm starting to see! :-)

The following take from http://java.sun.com/developer/technicalArticles/ALT/Reflection/ offers a Java approach for setting a field value given the name string. I too have been interested in similar tasks.

Changing Values of Fields

Another use of reflection is to change the values of data fields in objects. The value of this is again derived from the dynamic nature of reflection, where a field can be looked up by name in an executing program and then have its value changed. This is illustrated by the following example:

   import java.lang.reflect.*;
        
   public class field2 {
      public double d;
        
      public static void main(String args[])
      {
         try {
            Class cls = Class.forName("field2");
            Field fld = cls.getField("d");
            field2 f2obj = new field2();
            System.out.println("d = " + f2obj.d);
            fld.setDouble(f2obj, 12.34);
            System.out.println("d = " + f2obj.d);
         }
         catch (Throwable e) {
            System.err.println(e);
         }
      }
   }
