What is the use of final keyword in Java?

Question

Could someone tell me what is the use of the final keyword in Java?

Answer 1

A final keyword in Java could be defined as a variable that will be constant and cannot be changed. That means that value is final. For example, the value of Pi is 3.14…..This is used to restrict any alteration with that value. Final in Java could be applied in several contexts, like variable, method, and class, etc. If these are made final, then you cannot change the value of a variable, override a method, or extend the class.
