Question

I have a label which i need to create as per the size of my record
like if there are 2 records from database , my method should check and create 2 new labels at runtime , if 10 records there should be 10 labels to be created at run time
I am able to create 10 new labels at run time but how can i name them differently

some thing like

                 for (int i =0;i<array.size();i++)
                  {
                      Label lbl = new Label();
                  }

in this way there are 10 labels and showing perfectly , but all ten have the same name i.e lbl can this name could also be change like lbl1,lbl2,lbl3…
is it possible in GWT

Thanks

The thing you want to do isn’t poosible in any programming language.

The solution you are searching for is storing them inside a list and then access the labels via the index. Eg. if you want the first label you say List[0]

GWT supports such list, the easiast for you to use ist the ArrayList!

here is some more or less pseudo code:

    ArrayList<Label> labelList = new ArrayList<Label>();
    for (int i =0;i<array.size();i++)
    {
        Label lbl = new Label();
        labelList.add(lbl);
    }

    ...

    //the first item has the index 0!
    Label lbl1 = labelList.get(0);
    ..
    //doing stuff with the first label
    ...
    //getting the secont label
    Label lbl2 = labelList.get(1);

    ...
    //you get the idea right
