Question

In my current project, I want to convert List<String> to RegionLabel Object.

For instance, User enters String value one by one in order — center, floor, room . I am storing user’s input into List.

Now, my internal data structure in RegionLabel( String centerString, String floorString, String roomString);

My requirement is to convert List<String> data structure into RegionLabel("center", floor", "room" ); data structure.

One note:
My RegionLabel class is generated on-fly. On-fly means at design time, I do not know that “how many arguments RegionLabel constructors have?”

Answer 1

Create a new constructor like RegionLabel(List<String> list). This should do.

public RegionLabel(List<String> list) throws Exception{
     if( null == list || list.size() < 3 )
          throw new Exception("illegal parameter");
     this.centre = list.get(0);
      ...
}
