In what situations is the 'final' keyword used in programming?

The final keyword in Java is used to restrict modifications and is applied in several situations:

• Variables: A variable declared as final cannot be reassigned after initialization.

final int MAX_COUNT = 10;
// MAX_COUNT = 20; // compilation error

• Methods: A method declared as final cannot be overridden in subclasses.

• Classes: A class declared as final cannot have subclasses.

Using final helps improve code safety by preventing unintended changes and ensuring predictable behavior.
