The method Object(int) is undefined for the type Five

跟着别人写了一遍，我写就错了，有点无语，这是咋回事

import java.util.List;
import java.util.ArrayList;
public class He {
    public static void main(String[] args) {
        List list=new ArrayList<>();
        list.add(1);
        list.add(2);
        list.add(3);
        list.add(4);
        System.out.println(list);
        list.remove(Object(2));      //提示：The method Object(int) is undefined for the type Five
        System.out.println(list);
    }
}

将 list.remove(Object(2)); 改为：list.remove(2);
