Methods are made final due to design reasons.
Since private methods are inaccessible, they are implicitly final in Java..
Why we Cannot override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
Can we declare constructors as final?
No, a constructor can’t be made final. A final method cannot be overridden by any subclasses. As mentioned previously, the final modifier prevents a method from being modified in a subclass.
Can we inherit final method in Java?
No, we cannot override a final method in Java. The final modifier for finalizing the implementations of classes, methods, and variables. We can declare a method as final, once you declare a method final it cannot be overridden.

In short, an abstract class cannot be final in Java, using both abstract and final modifier with a class is illegal in Java. … An abstract method must be overridden to be useful and called but when you make the abstract method final it cannot be overridden in Java, hence there would be no way to use that method.
Can we override private and final methods?
No, We can not override private method in Java, just like we can not override static method in Java. … private methods are not even visible to Child class, they are only visible and accessible in the class on which they are declared. private keyword provides highest level of Encapsulation in Java.
Can private method be overridden as public method?
No, a private method cannot be overridden since it is not visible from any other class. You have declared a new method for your subclass that has no relation to the superclass method. One way to look at it is to ask yourself whether it would be legal to write super.
Can we override main method in Java?
No, we cannot override main method of java because a static method cannot be overridden. The static method in java is associated with class whereas the non-static method is associated with an object. … Therefore, it is not possible to override the main method in java.

Can constructor be private?
Yes, we can declare a constructor as private. If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.
Can a constructor override?
Constructor looks like method but it is not. It does not have a return type and its name is same as the class name. But, a constructor cannot be overridden. If you try to write a super class’s constructor in the sub class compiler treats it as a method and expects a return type and generates a compile time error.
Can we overload main method?
Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String args) method.
Can final method be overridden?
You use the final keyword in a method declaration to indicate that the method cannot be overridden by subclasses.
Can we override public method?
If a method cannot be inherited, then it cannot be overridden. A subclass within the same package as the instance’s superclass can override any superclass method that is not declared private or final. A subclass in a different package can only override the non-final methods declared public or protected.
Can we override static method?
Can we Override static methods in java? We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism. Hence the answer is ‘No’.
Can we have 2 main methods in Java?
A class can define multiple methods with the name main. The signature of these methods does not match the signature of the main method. These other methods with different signatures are not considered the “main” method. Yes it is possible to have two main() in the same program.
