Dynamic Vs Static Binding in Java

Hello Everyone, I'm currently doing an assignment for one of my classes, and in it, I have to give examples, using Java syntax, of  *static*  and  *dynamic binding*. I am lost while understanding the work process.

I understand the basic concept, that static binding happens at compile time and dynamic binding happens at runtime, but I can't figure out how they actually work specifically.

I found an example of static binding online that gives this example and running the program on interviewbit.

public static void callEat(Animal animal) {
    System.out.println("Animal is eating");
}

public static void callEat(Dog dog) {
    System.out.println("Dog is eating");
}

public static void main(String args[])
{
    Animal a = new Dog();
    callEat(a);
}

And that this would print "animal is eating" because  *the call to  `callEat`  uses static binding* , but I'm unsure as to  *why*  this is considered static binding.

So far none of the sources I've seen have managed to explain this in a way that I can follow. Can anyone suggest me?
