Java Literals
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. For example: byte a = 100; ----- char b= ‘B’; 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: “Helo My Name is Syed Ali Haider”; String and char types of literals can contain any Unicode characters. For example: Char n=’\u0001’; ------ String n= “\u0001”;
