Can main method be inherited ? If a super class has a main method and sub class doesn't have it, will the main method of the superclass is called ?

 

 

Yes.

 

 

can you just explain it more clearly ? As far as I know the static methods cannot be inherited and main is a static method. how can it be inherited ?

 

 

Static methods are inhereted. Run the following code.

public class Test {
	public static void main(String[] arg) {
		Test1.test();
		Test2.test();
		Test3.test();
	}
}
class Test1 {
	public static void test() {
		System.out.println("Test1");
	}	
}
class Test2 extends Test1 {
}
class Test3 extends Test1 {
	public static void test() {
		System.out.println("Test3");
	}	
}

 

 

Caveat:

                Test1 t0=new Test3();
                t0.test();

will yield "Test1", because t0's declared type is Test1, not Test3.

 

 

The best way to answer this question is to try it and see. It never fails to amaze me how often question like this get posted - it would probably be quicker and easier to just test than to come here, ask the question and wait for an answer. If you can't even manage that much on your own, then you aren't going to get very far as a Java developer.

By all means, once you've tried it for yourself, feel free to come here and ask about the results if they surprised you or you don't understand them, but asking "What would happen if I did this", when its something you could just do and find out, makes you seem a little pathetic (IMHO).



Explain what more clearly? You asked a yes/no question and got an answer (yes).



Well whoever told you that got it wrong.


A better question to have asked today might have been:
"I read last week that static methods aren't inherited, but I wrote some code that seems to demonstrate that in fact they are. At first I thought it was just the main method but then I tried with other static methods and found the same thing happened. Is it a special circumstance with certain static methods that I've stumbled across, or is what I was told last week just plain wrong? Here's some code to demonstrate what I did: <your code here>"

 

 

Thank you all for the answer.

 

 

I've made the mistake of saying that before. The correct answer is that static methods are inherited, but they are not polymorphic.
