如何反复迭代Array字段？

I have

Class<? extends Object> class1 = obj.getClass();
    Field[] fields = class1.getDeclaredFields();
    for (Field aField : fields) {
      aField.setAccessible(true);
       if (aField.getType().isArray()) {
          for (?? vals : aField) {
            System.out.println(vals);
          }
        }
      }
Class<? extends Object> class1 = obj.
