Java Literals – Types, Examples, and Explanation

In Java, literals are fixed values assigned to variables. They represent the actual data used in the code. Java supports different types of literals based on the data types.

Integer Literals	Represents whole numbers (decimal, binary, octal, or hexadecimal).	`10`, `0b1010`, `012`, `0xA`
Floating-Point Literals	Represents numbers with decimal points.	`3.14`, `1.5e2`, `0.0`
Character Literals	Represents single characters enclosed in single quotes.	`'A'`, `'1'`, `'\n'`
String Literals	Represents a sequence of characters enclosed in double quotes.	`"Hello"`, `"123"`
Boolean Literals	Represents logical values `true` or `false`.	`true`, `false`
