Why is main method static?
Why the main () method in Java is always static.
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.
In any Java program, the main() method is the starting point from where compiler starts program execution..
Can we inherit final class?
The final modifier for finalizing the implementations of classes, methods, and variables. The main purpose of using a class being declared as final is to prevent the class from being subclassed. If a class is marked as final then no class can inherit any feature from the final class. You cannot extend a final class.
Can main method be final?
Yes, we can declare the main () method as final in Java. The compiler does not throw any error. … The main use of the final method in Java is they are not overridden. We can not override final methods in subclasses.
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.
Are private methods final?
When we use final specifier with a method, the method cannot be overridden in any of the inheriting classes. Methods are made final due to design reasons. Since private methods are inaccessible, they are implicitly final in Java.
Can a final method be overridden?
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 .
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.
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 constructor 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 static method be overridden?
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.
Which methods can be overridden?
Instance methods can be overridden only if they are inherited by the subclass. 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.
Can we declare list as final?
4 Answers. You’re right that declaring the list final means that you cannot reassign the list variable to another object. … final as you know means that you cannot reassign the list variable another value.
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 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.
Why main method is not overridden?
Short answer is NO,we can not override main method in java. Reason is very simple.As main method is static and we know very well that we can not override static methods in Java,hence main method could not be overridden. So what will happen if we will try to override main method in subclass.
