Literals usually represent variables.

Explanation:


In programming, literals are fixed values that are directly written in the code. They are not variables or expressions, but rather the actual values themselves. They are used to represent known quantities or constants in a program.


While literals can represent known quantities, such as the number 5 or the string "Hello", they do not necessarily represent constants. Constants, on the other hand, are variables whose values cannot be changed once they are assigned. So, while literals can be used to initialize constants, they can also be used to represent variables that can change their values during the execution of a program.


Examples:


Let's consider the following examples:



  • Known quantities: In the statement int age = 10;, the literal value 10 represents a known quantity, the age of a person.

  • Variables: In the statement int x = 5;, the literal value 5 is assigned to a variable x. This means that the literal represents the value that the variable holds at a particular point in time. The variable x can be changed and take on different values during the execution of the program.

  • Constants: In the statement final int MAX_VALUE = 100;, the literal value 100 is used to initialize a constant MAX_VALUE. The constant represents a fixed value that cannot be modified later in the program.



Therefore, while literals can represent known quantities, constants, or variables, the most common usage is to represent variables that can have their values changed during program execution.
