final in Java

final is the modifier in Java applicable for classes, methods, and variables. If a class is declared as final then we can’t extend that class in other words we can’t create a child class for the final class i.e., inheritance is not possible with the final class.

If a method is final then we can not override that method.

If a variable declares as final then we can not update the value of a variable.

}
finally
