java - How can i visualize three nested List?

Question

I have a this structure:

List< List< tracciato >> dataTot;

with

public class tracciato {

   String              comando = "";
   String              nome;
   int                 posizione;
   String              tipo;
   ArrayList< String > dati = new ArrayList<>(); //  an other list 

   public tracciato() {
   }
}

note that also inside the class tracciato there is an other list.... they are 3 list nested...can I use dataTable? thanks for the suggestions.

Answer 1

我会选择类似的东西Tree，它会在控制台上看起来像这样：

List1
-List1_1
-- commando:
-- nome
---List1_1_1

and so on.

但是，如果您希望它是图形的，还有一个Tree可用的 Java 实现。
