The answer is no; there can only one “main” method – where “main” means an entry point you can “run”. You can code overloaded versions as in your example, but they can’t be “run”. You could have main methods in two different classes.
Can we write main method in more than one class?
Yes you can have more classes that contain public static void main(String args) . And you can chose to execute one class or another class. However, you can’t have more than one main method within same class.
Can we use multiple main methods in multiple classes 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 main method in Java?
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 declare main method as final?
The short answer is Yes. You can declare main method as final. without any compile error.
Can we execute a class without a main method?
Yes You can compile and execute without main method By using static block.
Can you overload the main method?
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.
Why main method is overloaded?
It is because the JVM executes the original main() method by default. Now the question arises that how we can invoke the overloaded main() method. To call the overloaded main() method, we must call it from the original main() method. Let’s understand it through an example.
Can main method be synchronized in Java?
Yes, the main can be synchronized in Java, a synchronized modifier is allowed in the main signature and you can make your main method synchronized in Java.
Is overriding possible in Java?
