Question

so if i understand correctly in the above example, a static method can be called by a class name so in the above example vehicle.horn(); would also work? without the static one would have to create An object vehicle v1 and use that object to call the method like v1.horn();

Answer 1

Exactly.
Non-static methods need an instance of the given class to call upon, like:

Object o = new Object();
o.getClass();
//Not like: Object.getClass();

While static methods can be called on the class itself, like:

String.format(...);
//Not like:
//String s = "example";
//s.format(...);

Non-static methods can access the instance they are called upon like:

void NotStatic() {
Object instace = this;
}

While the 'this' keyword cannot be used in static methods, because there is no instance the method is called on.

Answer 2

if this is the case they used the wrong example to make this clear in the above lesson...
