Getting the Field Objects of a Class Object
There are three ways of obtaining a Field object from a Class object. 

 Class cls = java.awt.Point.class;
     
 // By obtaining a list of all declared fields.
 Field[] fields = cls.getDeclaredFields();
     
 // By obtaining a list of all public fields, 
 // both declared and inherited.
 fields = cls.getFields();
 for (int i=0; i<fields.length; i++) {
   Class type = fields[i].getType();
   process(fields[i]);
 }
     
 // By obtaining a particular Field object.
 // This example retrieves java.awt.Point.x.
 try {
   Field field = cls.getField("x");
   process(field);
   } catch (NoSuchFieldException e) {
 }
