What are literals in Java? JavaObject Oriented ProgrammingProgramming

A literal is a source code representation of a fixed value. They are represented directly in the code without any computation.

Literals can be assigned to any primitive type variable.

Example

byte a = 68; char a = 'A'

byte, int, long, and short can be expressed in decimal(base 10), hexadecimal(base 16) or octal(base 8) number systems as well.

Prefix 0 is used to indicate octal, and prefix 0x indicates hexadecimal when using these number systems for literals. For example −

int decimal = 100; int octal = 0144; int hexa = 0x64;

String literals in Java are specified like they are in most other languages by enclosing a sequence of characters between a pair of double quotes. Examples of string literals are −

Example

"Hello World" "two\nlines" ""This is in quotes""

String and char types of literals can contain any Unicode characters. For example −

char a = '\u0001'; String a = "\u0001"; Johar Ali Updated on: 2019-07-30T22:30:20+05:30
