Hi!

I looked for the answer in Java Tutorial but could not find anything
useful.

Cheers

Can't directly; use octal or hexadecimal instead

Java can both read binary representations of numbers with Integer.parseInt(xxx,2) and write numbers in binary with Integer.toBinaryString(number).

So if I want to use for example 00010100 I write
int number = Integer.parseInt(00010100,2)?.

Almost, you need to use:

Code:

int number = Integer.parseInt("00010100",2);
