迭代字段是多余的

但是为啥age是integer包装类型，不是应该是int基本类型么，换类型把扩展性搞没了

public static void main(String[] args) throws Exception {
   String name = "Xiao Ming";
   int age = 20;
   Person p = new Person();
   Class cls = p.getClass();
   Object[] arg = new Object[] {age,name};
   Method[] ms = cls.getDeclaredMethods();

   for (Object a: arg) {
      var n = a.getClass().getName();
      if (n == "java.lang.Integer") {
         n = "int";
      }
      //找到对应参数类型的方法，填入参数      
      for (Method m: ms) {
         try{
            var para =  m.getParameterTypes()[0].getName();
            if (para.equals(n)) {
               m.invoke(p, a);
            }
         } catch (ArrayIndexOutOfBoundsException e) {
            System.out.println(e);
         }
      }
   }

自动装箱懂不，兄弟。你用的是一个Object数组将int类型的age和String类型的name装进去，而int类型的age会自动装箱为Integer类型`

别拿你认为的语言某方面用起来方便就说其他语言的不方便，存在就有它的合理性
