Do I need to cast to String when adding an Integer or a Double to a String?

Question

If I have

'String t = "";
int i = 1;
double d = 3.3;'

May I do t = t + " " + i + " " + d or I need to cast?

I tried it and it worked, but I still wanted to understand if this was just an incorrect but working trick or the real good way of programming. — Tatanan, Apr 02 '14 at 11:38

Yes you can..No need to cast..

Simply you can do like you said, t = t + " " + i + " " + d;

No. You don't

t = t + " " + i + " " + d --> "New" String = string + " " + String.valueOf(integer) + " " + String.valueOf(double)

I have 2 answers, one saying I can, one saying I can't. I know both work, but is this one more correct or equivalent? – Tatanan Apr 02 '14 at 11:40

@Tatanan - I meant.. "No, you don't have to cast it". – TheLostMind Apr 02 '14 at 13:26

Try it :

    double total = 10; 
    String total = String.valueOf(total);
