Can we override the main method?
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 methods be final in Java?
You can declare some or all of a class’s methods final. You use the final keyword in a method declaration to indicate that the method cannot be overridden by subclasses. The Object class does this—a number of its methods are final .
What is the difference between private and final in Java?
The main difference between private and final keyword in Java is that private is primarily an access modifier, which controls the visibility of variable, method, and classes in Java application, while final is just a modifier that enforces additional constraints on the field, method, and class in Java.
Can a constructor be final?
No, a constructor can’t be made final. A final method cannot be overridden by any subclasses. … But, in inheritance sub class inherits the members of a super class except constructors. In other words, constructors cannot be inherited in Java therefore, there is no need to write final before constructors.
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 we overload private and final methods?
private and final methods can be overloaded but they cannot be overridden. It means a class can have more than one private/final methods of same name but a child class cannot override the private/final methods of their base class. … Argument list should be different while doing method overloading.
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 override static method?
Can we override a static method? No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. So, we cannot override static methods.
Can we override private method in Java?
No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.
Can Final methods be overridden?
Any method that is declared as final in the superclass cannot be overridden by a subclass.
Are private methods final?
Since private methods are inaccessible, they are implicitly final in Java. So adding final specifier to a private method doesn’t add any value.
