Question

Possible Duplicate:
In Java, can I define an integer constant in binary format?

In python, you can do something like:

a = 0b00000010 which would set a to 2.

Is it possible to do something like that in Java? I know I could just go through and assign my varibles by the number instead of binary, but I like the visual.

Thanks ~Aedon

Answer 1

In Java 7, you can do

int a = 0b00000010;

However if you’re working with an older version, I’m afraid you’re stuck with

int a = Integer.parseInt("00000010", 2);
