how do i declare an int in binary format?

[Thomas Paul]

What do you want to do? Load it with a binary value or print out the result as a binary value?

The Integer class has a couple of static methods that handle what you are trying to do:

String base2 = "100011";
System.out.println("binary to int: " + Integer.parseInt(base2, 2));
int base10 = 35;
System.out.println("int to binary: " + Integer.toBinaryString(base10));

HTH,
Joe

Update: As of Java 7, you can declare binary numbers with this syntax:

int bitMask = 0b0101101;

[Bear Bibeault]

To avoid any confusion, that syntax in no way changes how the int is stored or how the int is declared. All that notation does is to allow numeric littorals to be expressed as binary number. No mre and no less.
