Java – In Java, can I define an integer constant in binary format

binaryjavasyntax

Similar to how you can define an integer constant in hexadecimal or octal, can I do it in binary?

I admit this is a really easy (and stupid) question. My google searches are coming up empty.

In Java 7:

int i = 0b10101010;

There are no binary literals in older versions of Java (see other answers for alternatives).

For reference—future Python possibilities:
Starting with Python 2.6 you can express binary literals using the prefix 0b or 0B:

>>> 0b101111
47

You can also use the new bin function to get the binary representation of a number:

>>> bin(173)
'0b10101101'

I found a one-line solution from the good old Apache Commons Lang library.
ArrayUtils.addAll(T[], T...)

Code:

String[] both = ArrayUtils.addAll(first, second);
