[問題] Number Wrapper & method overloading

[uopsdod (pcman)]

public class Prac extends Test2{

        public static void go(Long n){
                System.out.println("Long ");
        }
        public static void go(Short n){
                System.out.println("Short ");
        }
        public static void go(int n){
                System.out.println("int ");
        }

        public static void main(String[] args) throws IOException{
                short y = 6;
                long z = 7;
                go(y);
                go(z);
        }
}

What is the result?

Answer:

int Long



為何是這樣,我本來以為會autoboxing變成 Short?

推 kyleJ: main裡面的short是基本型態 比起自動裝箱 Java會先尋找自
→ kyleJ: 動寬化後符合的型態吧
→ uopsdod: 原來是這樣,了解了感謝!
