How to write something in binary and assign it to a variable? [duplicate]

Question

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

You could wait for Java7, that supports binary literals (for some inexplicable reason) — skaffman

@skaffman: It's inexplicable that Java would support binary literals? Is there a more self-documenting way of showing int masks in code? — Mark Peters

@ratchet freak - Nothing is wrong with it. But I am doing bitmask flags and wanted to visualize how the flags were laid out. Preference is in question here not functionality. — ahodder

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);

or you can write in hex using 0x int i = 0x10; which is equal to int i = 16;
