Can the main () method be overloaded or overridden?

Overriding main method

You cannot override static methods and since the public static void main() method is static we cannot override it.

Can we overload main method in Java by changing the parameters?

Yes, we can overload the main method in Java, i.e. we can write more than one public static void main() method by changing the arguments.

Can we have 2 main methods in Java?

From the above program, we can say that Java can have multiple main methods but with the concept of overloading. There should be only one main method with parameter as string[ ] arg.

Can we overload constructor?

Constructors can be overloaded in a similar way as function overloading. Overloaded constructors have the same name (name of the class) but the different number of arguments. Depending upon the number and type of arguments passed, the corresponding constructor is called.

Can we overload a main() method in Java? || Java Interview Question

Can we overload main method in C++?

so to conclude: in c++ global main cannot be overloaded it will generate compile time error, in is because you cannot have multiple entry point for the same program as said above.

Can we overload static method?

Can we overload static methods? The answer is 'Yes'. We can have two or more static methods with the same name, but differences in input parameters.

Can we override and overload the main () method in a Java class briefly explain your statement?

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 overload the main method say class A has one main method and class B has another main method How do you call class A's main method from class B?

Yes, you can.

The normal main method acts as an entry point for the JVM to start the execution of program. execute the overloaded main method when we run your program, we need to call the overloaded main method from the actual main method only.

Can we overload main method What happens when overloaded?

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 we override the main method and why?

Here a question arises that like the other methods in Java, can we also overload the main() method. The answer is, yes, we can overload the main() method. But remember that the JVM always calls the original main() method. It does not call the overloaded main() method.

Can we overload final method?

Can We Override a Final Method? No, the Methods that are declared as final cannot be Overridden or hidden.

Can we overload methods on return type?

No, you cannot overload a method based on different return type but same argument type and number in java.

Can we override final method?

Any method that is declared as final in the superclass cannot be overridden by a subclass.

Can main () function be made private?

Can main() function be made private? Explanation: The reason given in option “No, because main function is user defined” is wrong. The proper reason that the main function should not be private is that it should be accessible in whole program.

Can we create 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 a C++ class have an object of self type?

A class declaration can contain static object of self type, it can also have pointer to self type, but it cannot have a non-static object of self type.

Can we change return type in overriding?

Java version 5.0 onwards it is possible to have different return types for an overriding method in the child class, but the child's return type should be a subtype of the parent's return type. The overriding method becomes variant with respect to return type.

Can we overload a method in Java?

In Java, two or more methods may have the same name if they differ in parameters (different number of parameters, different types of parameters, or both). These methods are called overloaded methods and this feature is called method overloading.

Is overriding possible in Java?

In Java, method overriding occurs when a subclass (child class) has the same method as the parent class. In other words, method overriding occurs when a subclass provides a particular implementation of a method declared by one of its parent classes.

Can we overload private methods?

Yes, we can overload private methods in Java but, you can access these from the same class.

Can we override the private methods?

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.

What we Cannot overload in Java?

We cannot overload two methods in Java if they differ only by static keyword (number of parameters and types of parameters is same).

Why main method is 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 write static public void main String args?

Yes, we can change the order of public static void main() to static public void main() in Java, the compiler doesn't throw any compile-time or runtime error. In Java, we can declare access modifiers in any order, the method name comes last, the return type comes second to last and then after it's our choice.
