What purpose does "overriding" main serve in Java?

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??

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.

I dont think you can override main in Java because you don't inherit main from any class in the first place. Hence there is nothing to be overriden.

Overriding is not for STATIC functions, overriding is only for member functions which are not static.

In this case, No POLYMORPHIC will be observed.
