Which of these keywords is used to prevent content of a variable from being modified?Select one:finallaststaticconstant

Answer

The keyword used to prevent the content of a variable from being modified is constant.

Explanation

1. Final: In Java, the final keyword is used to define constants, meaning that once a variable is assigned a value, it cannot be modified in the future. However, it is only relevant for variables, methods, or classes in Java, and does not directly translate to a keyword used universally across programming languages.

2. Last: This is not a standard keyword in most programming languages for preventing modification.

3. Static: While static is used to indicate that a variable or method belongs to the class rather than instances of the class, it does not prevent its modification.

4. Constant: In programming, a constant is specifically designed to hold values that cannot change throughout the program execution, making it the most fitting answer.

Thus, in multiple programming contexts, the concept of a "constant" serves this purpose effectively.
