@FunctionalInterface hashcode It's the same every time?

Question

    public static void main(String[] args) {
        Function function = o -> "111";
        System.out.println("hashCode:" + function.hashCode());

        Function function2 = o -> "111";
        System.out.println("hashCode:" + function2.hashCode());
    }

hashCode:1560911714 hashCode:1237514926

Repeat execution:

hashCode:1560911714 hashCode:1237514926
