What if main method is declared private in java

PrivateMain Main method not public. PublicMain Hello, I'm proctected and I'm running In this code, the protected method can't be used as entry point of the app, but, it can be invoked from the class PublicMain Private methods can't be invoked but from the class it self. Improve this answer. OscarRyz OscarRyz k gold badges silver badges bronze badges. Michael - the only method signature recognized by java as an entry point is static void main String[].

Methods with any other name than main , any parameter types or a non- void return type are NOT recognized and never have been. Stephen C : Thanks for pointing that out I think I was confused the Java entry point with other languages Yeah, that must be C : — Michael Mao.

Yes, it will compile. But it wil not run as entry point of the program. Karthik Karthik 1, 2 2 gold badges 11 11 silver badges 13 13 bronze badges. Matthew Flaschen Matthew Flaschen k 47 47 gold badges silver badges bronze badges.

It will compile, it will not run tested using Eclipse. Chris Dennett Chris Dennett It will give you the following errors Error: Main method not found in class A, please define the main method as: public static void main String[] args or a JavaFX application class must extend javafx.

What is covariant return type? What is the result of the following statement? What is externalization? Where is it useful?? Use the Externalizable interface when you need complete control over your Bean's serialization for example, when writing and reading a specific file format.

Which class is the superclass for every class. Which Container method is used to cause a container to be laid out and redisplayed? What's the difference between a queue and a stack? You can create an abstract class that contains only abstract methods. On the other hand, you can create an interface that declares the same methods.

So can you use abstract classes instead of interfaces? What comes to mind when you hear about a young generation in Java? What comes to mind when someone mentions a shallow copy in Java?

If you're overriding the method equals of an object, which other method you might also consider? You are planning to do an indexed search in a list of objects. How would you make a copy of an entire Java object with its state? How can you minimize the need of garbage collection and make the memory use more effective? It searches for the main method which is public, static, with return type void, and a String array as an argument. Can we declare main method as private or protected or with no access modifier in java?
