A binary literal is a number that is represented in 0s and 1s (binary digits). Java allows you to express integral types (byte, short, int, and long) in a binary number system. To specify a binary literal, add the prefix 0b or 0B to the integral value. So, we can express binary digits in a program by assigning them to variables, and the output of those variables after executing the program will be decimal digits.
Implementing Binary literals in Java:
We can explore the ways in which we can implement and use binary literals in Java programming language. The first and following Java program is an example to implement different types of binary literals. As mentioned above Java allows us to express byte, short, int, and long types of binary literals.
Java
// Java Program to Illustrate Use of Binary Literalspublic class GFG {    public static void main(String[] args)    {        // Byte type Binary Literal        byte a1 = 0b011;          // The b can be lower or upper case        byte a2 = 0B101;        System.out.println("Binary Literal in Byte----->");        System.out.println("a1 = " + a1 + ", "                           + "a2 = " + a2);          // Short type Binary Literal        short b1 = 0b101;          // The b can be lower or upper case        short b2 = 0B111;        System.out.println("Binary Literal in Short----->");        System.out.println("b1 = " + b1 + ", "                           + "b2 = " + b2);          // Int type Binary literal        int c1 = 0b011;          // The b can be lower or upper case        int c2 = 0B111;        System.out.println(            "Binary Literal in Integer----->");        System.out.println("c1 = " + c1 + ", "                           + "c2 = " + c2);          // Long type Binary literal        long d1 = 0b0000011111100011;          // The b can be lower or upper case        long d2 = 0B0000011111100001;          System.out.println("Binary Literal in Long----->");        System.out.println("d1 = " + d1 + ", "                           + "d2 = " + d2);    }} |
Binary Literal in Byte-----> a1 = 3, a2 = 5 Binary Literal in Short-----> b1 = 5, b2 = 7 Binary Literal in Integer-----> c1 = 3, c2 = 7 Binary Literal in Long-----> d1 = 2019, d2 = 2017
In Java, operators can be used on binary literals to perform operations. The following Java program is an example to implement different mathematical and comparison operations on binary literals. The results of these operations on binary literals are decimal digits.
Java
// Java Program to Illustrate Use of Binary Literalspublic class GFG {    public static void main(String[] args)    {        byte n1 = 3; // Decimal number        byte n2 = 0b011; // Binary of 5        byte n3 = -0b111; // Negative binary number        byte n4 = 0b1101;          System.out.println("n1 = " + n1);        System.out.println("n2 = " + n2);        System.out.println("n3 = " + n3);        System.out.println("n4 = " + n4);          // Checking if the decimal and binary digits are        // equal        System.out.println("is n1 and n2 equal: "                           + (n1 == n2));        // Adding 1 to a binary digit        System.out.println("n2 + 1 = " + (n2 + 1));          // Adding 1 to a negative binary digit        System.out.println("n3 + 1 = " + (n3 + 1));          // Multiplying 2 with a binary digit        System.out.println("n4 x 2 = " + (n4 * 2));    }} |
n1 = 3 n2 = 3 n3 = -7 n4 = 13 is n1 and n2 equal: true n2 + 1 = 4 n3 + 1 = -6 n4 x 2 = 26
