Question

I’m using this code to set the id of any button:

String s = "" + i + j;
int getal = Integer.parseInt(s);
button.setId(getal);

Variables “i” and “j” are always from 0 tot 9. A single digit. However, if “i” is 0 then the parseInt() method deletes it, I think.

For example: when i=0 and j=6 the outcome of variable “getal” wil be 6 and not 06. I need it to be 06. Does somebody maybe know an other way of converting strings to ints?

Answer 1

An Integer can’t be “06” – it is either 6 or it is a String.

So, the setId will not see any difference between “06” and “6”.

If you really need the leading Zero, you could either save it as a String or as an int[]
