 public static <T> T setParam(Class<T> clazz, Object[] args)        
      throws Exception {      
         if (clazz == null || args == null) {       
               throw new IllegalArgumentException();         
               }         
               T t = clazz.newInstance();         
               Field[] fields = clazz.getDeclaredFields();         
               if (fields == null || fields.length > args.length) {        
                    throw new IndexOutOfBoundsException();         
                    }         
                    for (int i = 0; i < fields.length; i++) {       
                          fields[i].setAccessible(true);             
                          fields[i].set(t, args[i]);         
                          }         
                          return t;     
                          }
