}

}

class apples{

public static void main(String args[]){

tuna tunaObject = new tuna();

System.out.println(tunaObject.toMilitary());

System.out.println(tunaObject.toString());

tunaObject.setTime(13,27,6);

System.out.println(tunaObject.toMilitary());

System.out.println(tunaObject.toString());

}

}
