[Java Reflection REVIEW] 자바 리플렉션 사용기- 01

I'm a Java developer. As a Java developer. There are many annoying things in workspace while I'm working. Such as Using MAP!!!! Let's say. You're going to put Info data into Map

Info info = new Info("name", "password", "alias", "address", "strength",
                     "etc1", "etc2");

Map map = new HashMap();
map.put("name",info.getName());
map.put("password",info.getPassword());
map.put("alias",info.getAlias());
map.put("address",info.getAddress());
map.put("strength",info.getStrength());
map.put("etc1",info.getEtc1());
map.put("etc2",info.getEtc2());

I've found tons of lines of codes In my workspace. As a junior Programmer, By the way I've worked as a programmer just about 5 months, I asked my comapany "How can we fix it? This is really annoying?" But they said "I don't know Why you are asking. This is What it is. It is not an error." So I've tried using Java Reflection. It is very Simple that you can easily use it. first. Create Getters

private String craeteGetMethod(String arg) {
 StringBuffer buffer = new StringBuffer(10);
 buffer.append("get");
 buffer.append(arg.substring(0, 1).toUpperCase());
 buffer.append(arg.substring(1));
 return buffer.toString();
}

Simple so When You put "name" in it. You'll get "getName". Second. Create Invoking Method

private String invokeMethod( String methodName, Object obj) {
  String res = null;
    Method me;
      try {
    
 me = obj.getClass().getMethod(methodName);
 res = (String)me.invoke(obj);
    
 } catch (Exception e) {
   e.printStackTrace();
 }

    return res;
}

Third. Gather Method and Invoke All

private void ObjectToMap(Map map, List methods, Object sms) {
  for ( String key : methods) {
    String methodName = craeteGetMethod(key);
    invokeMethod(methodName, sms);
    map.put(key, invokeMethod(methodName,sms));
  }
}

I should have finished refactoring. but this will be enough in this page.

Info info = new Info("name", "password", "alias", "address",
 "strength", "etc1", "etc2");

Map map = new HashMap();
ObjectToMap(map, Arrays.asList("name", "password", "alias",
 "address", "strength", "etc1", "etc2"), info);

But It's really slow If you are going yo use reflection to put a massive datas into Database. This is not for you. thank you for stopping by. I will be happy with your comments.
