Wht does this work?

Question

How come this:

class MyClass {

static void sayHello() {
System.out.println("Hello World!");
}

public static void main(String[ ] args) {
sayHello();
}
}
// Outputs "Hello World!"

Works even though I didn't include the class name?

Answer 1

It is within the same class so doesn't need to called via the class name. It's optional in this case.
