Question

how can i get for example the integer codeInt=082 from String code=’A082′
i have tried this:

int codeInt = Integer.parseInt(code.substring(1,4));

and i get codeInt=82 ,it leaves the first 0 but i want the full code ‘082’.

i thought of parseInt(String s, int radix) but i don’t know how .

any help will be appreciated .
thanks.

An integer just stores a number. The numbers 82 and 082 (and 0082 and 000000082 for that matter) are exactly the same (unless you put them into source code in some languages in that manner, then you’ll get a compiler error)¹.

If you desperately need the leading zero, then you should either leave it as a string, or format the number appropriately for output later.
