Question

What is a literal in Java?

Answer 1

The literal is a value that can be written directly to a data type .
Example : String s = new String ("Hello"); // It's not a literal
String s = "Hello"; // It's a literal
that means you don't call the Constructor of the Class to define an object.

The literals can be applied to any data type : integer , float , double , boolean , String.

Float Example:
Float num = new Float (4); // It's not a literal
Float num = 4f; // It's a literal
