Question

this is how we can override main function in java….

public class animaltest 
{
    public static void main(String[] args)  
    {
        horse h = new horse();
        h.eat();
    }
}

public class inheritmain extends animaltest 
{
    public static void main(String[] args)  
    {
        System.out.print("main overrided");
    }
}

but what is the benefit of overriding main??

Answer 1

static methods do not override: they are shadowed. There are two different independent static methods in that case, namely animaltest.main and inheritmain.main. (See Can we override static method in Java?)

The “advantage” — if any 😉 — is that the program can be started/launched from either class as both classes implement the main method:

The main method is similar to the main function in C and C++; it’s the entry point for your application and will subsequently invoke all the other methods required by your program.

Happy coding.
