Question

I have the following method and I need to return two strings:

1. value of type.getName()
2. value of field.getName()

What is the best way to do it?

public static void getClassMetaData(List<Object> listClsObj) {
    ....

    for (Field field : declaredFields) {
         Class<?> type = field.getType();

         System.out.println(type.getName());
         System.out.println(field.getName());
      }
}

Answer 1

I would rather return just the Field, since you can get the type and other information from the field itself.

And then at the point of invocation, call the method – field.getType() to get the type.

Seems like you are working with all the declared fields of your class, in which case you can just return the List<Field>: –

public static List<Field> getClassMetaData(List<Object> listClsObj) {

    // Rather than iterating over `declaredField`, just return it
    return declaredFields;
}
