Java Basic(41)-Building Objects for Constructors

class apples{

public static void main(String args[]){

tuna tunaObject = new tuna();

tuna tunaObject2 = new tuna(5);

tuna tunaObject3 = new tuna(5,13); →我們這裡有4個對象(object)

tuna tunaObject4 = new tuna(5,13,43);

System.out.printf("%s\n", tunaObject.toMilitary());

System.out.printf("%s\n", tunaObject2.toMilitary());

System.out.printf("%s\n", tunaObject3.toMilitary());

System.out.printf("%s\n", tunaObject4.toMilitary());

}

}

我們有4個對象，因為在tuna.class有4個constructor

這是運行時的結果：

00:00:00

05:00:00

05:13:00

05:13:43
