Literals

Literals are constant values written directly in the code. They represent fixed values assigned to variables.

Example:

int a = 10;
int b = 20;
int c = scan.nextInt();
System.out.println("Hello, World!");

Explanation:

In the above example:

  • 10 and 20 are integer literals
  • "Hello, World!" is a string literal
  • scan.nextInt() is not a literal — it's a method call.

Note:

From Java 7 onwards, the underscore (_) is allowed in numeric literals (except at the beginning or end of the number or next to a decimal point) to improve readability 

❌ Invalid:
int salary = 95,000;   // Comma is not allowed in numeric literals

✅ Valid:
int salary = 95_000;   // Underscore used for readability

You can use underscores in:

  • Integer literals
  • Floating-point literals
  • Binary, Hex, and Octal numbers

Summary:

  • Literals are constant fixed values in Java code.
  • They can be of types like int, float, char, string, boolean, etc.
  • Underscores can be used in numeric literals to improve readability (since Java 7).
  • Do not confuse method calls or variable names with literals.
