Question

I have this object Object1 defined as public Object1(String item, List<Object2> obj2) in a class (whilst Object2 is defined in another class as public Object2(String item1, String item2))

Next, in the main program, I’m creating a list of Object1 objects:

public static List<Object1> obj1 = new List<Object1>();

List<Object2> obj2 = new List<Object2>();:

obj1.add("first", obj2);
obj1.add("second", obj2);
obj1.add("third", obj2);

Next I want to add some objects into obj2 for every obj1 specifically:

obj1[0].Obj2.Add(new Object2("first","first");
obj1[0].Obj2.Add(new Object2("first","second");
obj1[1].Obj2.Add(new Object2("second","first");
obj1[1].Obj2.Add(new Object2("second","second");
obj1[2].Obj2.Add(new Object2("third","first");
obj1[2].Obj2.Add(new Object2("third","second");

Now the problem is that, for example, obj[0].Obj2.Count is 6, and it’s the same for obj[1].Obj2.Count and so on. How should I populate obj2 so that each Obj2 would be different depending on obj1[]? For example obj1[0].Obj2 different from obj1[1].Obj2 and obj1[0].Obj2.Count to be 2.

Please excuse me if I didn’t explain my problem properly or didn’t write all the necessary details. Thank you for your answers in advance.

If I understand you well, you should have a different list for each Object1

obj1.add("first", new List<Object2>());
obj1.add("second", new List<Object2>());
obj1.add("third", new List<Object2>());

Have you considered using a Map ?
