Can we overload main method?

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 a main method be 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 overload and override the main method?

Yes, We can overload the main method in java but JVM only calls the original main method, it will never call our overloaded main method.

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 a main() method in Java? || Java Interview Question

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 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 declare main method as final?

Yes, we can declare the main () method as final in Java. The compiler does not throw any error. If we declare any method as final by placing the final keyword then that method becomes the final method. The main use of the final method in Java is they are not overridden.

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 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.

What happens if I remove static from main method?

1 Answer. If you don't add the 'static' modifier in your main method definition, the compilation of the program will go through without any issues but when you'll try to execute it, a "NoSuchMethodError" error will be thrown.

Can we overload static and non static method together?

Yes they can overload each other.

Can we declare main () method as non static?

You can write the main method in your program without the static modifier, the program gets compiled without compilation errors. But, at the time of execution JVM does not consider this new method (without static) as the entry point of the program.

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.

Why do we pass String args in main method?

When you run Java program, by right click on Java class with main method, it creates a Run Argument for that class. By the way, you can write your String args[] as String[] args as well, because both are valid way to declare String array in Java.

Can main method be abstract?

Ans. No. Static methods cannot be overridden and hence make no sense to be declared abstract.

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.

Why main method is overloaded?

Yes, main method can be overloaded. Overloaded main method has to be called from inside the "public static void main(String args[])" as this is the entry point when the class is launched by the JVM. Also overloaded main method can have any qualifier as a normal method have. Show activity on this post.

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 we override private method?

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 we overload final method in Java?

yes overloading final method is possible in java.As final methods are restricted not to override the methods. while overloading argument list must be different type of the overloading method.

Can we overload abstract method in Java?

Yes, you can have overloaded methods (methods with the same name different parameters) in an interface.

Can we overload constructor in derived class?

Since the constructors can't be defined in derived class, it can't be overloaded too, in derived class.

Can we write main method without void?

Yes. Things like libraries don't have a main method. The main method is the entry point for the program, so you'll have to have a main method somewhere or the code won't execute, but not necessarily in any given Java file.
