The informal intuition is that one method is more specific than
another if any invocation handled by the first method could be passed
on to the other one without a compile-time error.
Consider movie(int...x) as M1 and movie(double...x) as M2.
Method M1 is more specific than M2 because we can call method M2 with the same inputs given to the method M1 directly without any compile time errors.
So, invocation on first method M1 is defineitly handled by the M2. Because double can handle int without any problem.
But we can not invoke M1 with the same inputs given to the method M2 and that is easy to understand.
Let's check following example,
public class Test {
public static void main(String[] args) {
movie();
}
static void movie(int... x) {
System.out.println("One argument");
}
static void movie(short... x) {
System.out.println("Short argument");
}
}
OUTPUT
Short argument
Because here short is more specific than int for method call movie().
On the other hand for boolean method call movie(); raise the confusion, because compiler can not decide which method to call because in this case there is no such point of more specific method.
