Binary Literals
In Java 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.
Java binary literals example
package com.w3schools; public class Java7BinaryLiterals { public static void main(String args[]){ int i=0b01111; byte b=(byte) 0b01111; long l=(long) 0B01111L; System.out.println("i="+i); System.out.println("b="+b); System.out.println("l="+l); } }
Output
i=15 b=15 l=15
