hello

can you explain me this, why BiConsumer<String, Integer> accepts method having double primitive type argument and prints double not integer:

Code: Select all

... main code...

        BiConsumer<String, Integer> biConsumerMR = MyClass::showNameAge;
        biConsumerMR.accept("bob", 50);
    }
... end main...

    static void showNameAge(String name, double age){
        System.out.println(name+" "+age);
    }
