Why (static,void) dose not allowed befor main class Myname

Question

public class Animal {
static void bark() {
System.out.println("Woof-Woof");
}
}

static class MyName {
public static void main(String[ ] args) {
Animal dog = new Animal();
dog.bark();
}
}

Answer 1

Simply because static methods must be used with class name. You don't need to create an instance of Animal to use the bark method.
A static method can be used with: MyClassName.myStaticMethod(), without instance of MyClassName. In your case, to use the bark method, you must do: Animal.bark().
Or if you want to use an instance (dog, in your case), only remove the static keyword of the bark method, and replace it by "public" :)
