Introduction

In Java SE 7, the integral types (byte, short, int, and long) can also be expressed using the binary number system.

To specify a binary literal, add the prefix 0b or 0B to the number.

The following examples show binary literals: 

// An 8-bit 'byte' value:
byte aByte = (byte)0b00100001;

// A 16-bit 'short' value:
short aShort = (short)0b1010000101000101;

// Some 32-bit 'int' values:

int anInt1 = 0b10100001010001011010000101000101;
int anInt2 = 0b101;
int anInt3 = 0B101; // The B can be upper or lower case.

// A 64-bit 'long' value. Note the \"L\" suffix:
long aLong = 0b1010000101000101101000010100010110100001010001011010000101000101L;

you need to cast short and byte, but not int. Long is suffix.
