%% I have this example of code

     for i = 1:1:10
        T = randi([0 10],1,1); % random number between 0 and 10
        R = num2str(T);
        listbox1.add(i,R);   %%this line is adding only one number to the list
        %%I want to add all these numbers in the JList
     end

The first step is working now. I have a textfield in the Figure. I want to write the selected number in that textfield.

See attached File to understand.

In this last version, the selected item index is reported on the textfield. I want the item string, not its index.

Try this:

numItems = 10;
for k = 1 : numItems
  T = randi([0 10],1,1); % random number between 0 and 10
  oneCell = {sprintf('%d', T)};
  listboxItems(k) = oneCell;
end
% Optionally, print cell array to command window so we can see it.
celldisp(listboxItems)
% Send this cell array to the listbox
set(handles.listbox1, 'String', listboxItems);
