Can we override the static methods?
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 execute static block without main method?
Yes You can compile and execute without main method By using static block. But after static block executed (printed) you will get an error saying no main method found.
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 final method be overloaded?
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.
What is method hiding?
Method hiding means subclass has defined a class method with the same signature as a class method in the superclass. In that case the method of superclass is hidden by the subclass. It signifies that : The version of a method that is executed will NOT be determined by the object that is used to invoke it.
Which method Cannot be overridden?
A method declared final cannot be overridden. A method declared static cannot be overridden but can be re-declared. 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.
Can we inherit private method in Java?
You can only call a private member method in its definition class. … say() because derived classes can’t inherit private methods from its base class. Only protected and public methods/variables can be inherited and/or overridden.
Why we use static in main method?
Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class. … Static method of a class can be called by using the class name only without creating an object of a class.
Is it possible to override the main method?
In short, the main method can be overloaded but cannot be overridden in Java. That’s all about overloading and overriding the main method in Java. Now you know that it’s possible to overload main in Java but it’s not possible to override it, simply because it’s a static method.
Can we execute a program without main () method?
Yes, we can execute a java program without a main method by using a static block. Static block in Java is a group of statements that gets executed only once when the class is loaded into the memory by Java ClassLoader, It is also known as a static initialization block.
Can you make a constructor final?
No, a constructor can’t be made final. A final method cannot be overridden by any subclasses. … In other words, constructors cannot be inherited in Java therefore, there is no need to write final before constructors.
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.
