why this code is not running without "static" word?

Question

when there are two class and I am using object this code is running without word static before void, but when I edit it and use just one class it didn't run without "static" before void. And why this is happening explain please ☺

original code : https://www.sololearn.com/learn/Java/2155/

Edited code :

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

}

public static void main(String[ ] args) {

bark();
}
}

Answer 1

If u don't write static then u need to create an object of it!
but with static u don't.

That's why, ur code is not running because u have removed static but not created an object.

Hope this helps!!!

Answer 2

static methods belong to the class and not the instance of it so without static you would have to call it using

Animal x = new Animal();
x.bark()

and with static you would call the class method like so

Animal.bark();

Like Mayank Rampuriya said you do not need to create a instance of it if its static
