how to work with other base numbers in java?

Question

Guys if the int c=10001; which is a binary value.If i want to process it like multiplying it by 10 how to do that?

Answer 1

If I understand you correctly you want to do this: Integer.parseInt("10001", 2), which will give you 17.
Integer.toString also accepts radix as second argument.

Doc: Integer.parseInt(String s, int radix)
