Compilation error: Need Help

Question about the task

Under discussion

I continue to receive the following error message, and I can't figure out why: com/codegym/task/task13/task1328/Solution.java:27: error: cannot find symbol robotFirst.getName(), robotSecond.getName(), attacked, defended)); ^ symbol: method getName() location: variable robotFirst of type com.codegym.task.task13.task1328.AbstractRobo

1. Familiarize yourself with the code.
2. Accept your fate and keep trying to understand the code.
3. ...
4. Rejoice that you've figured it out.
5. Adapt the code to the following new architecture and add new logic:
5.1. Make the AbstractRobot class abstract. Then move the attack and defend logic from the Robot class to the AbstractRobot class.
5.2. Edit the Robot class to utilize the AbstractRobot class.
5.3. Extend the BodyPart class with a new body part: BodyPart.CHEST.
5.4. Add the new body part to the implementation of the CanAttack and CanDefend interfaces (in the AbstractRobot class).

Requirements:

The AbstractRobot class must be abstract.
The AbstractRobot class must implement the CanAttack and CanDefend interfaces.
The Robot class must inherit the AbstractRobot class.
The logic defining the how a Robot behaves must be in the AbstractRobot class.
The BodyPart class must have and initialize a final static BodyPart variable called CHEST.
The new body part must be added to the logic for the attack and defend methods in the AbstractRobot class.

package com.codegym.task.task13.task1328; /* Robot wars */ public class Solution { public static void main(String[] args) { Robot amigo = new Robot("Amigo"); Robot enemy = new Robot("Enemy"); doMove(amigo, enemy); doMove(amigo, enemy); doMove(enemy, amigo); doMove(amigo, enemy); doMove(enemy, amigo); doMove(amigo, enemy); doMove(enemy, amigo); doMove(amigo, enemy); } public static void doMove(AbstractRobot robotFirst, AbstractRobot robotSecond) { BodyPart attacked = robotFirst.attack(); BodyPart defended = robotFirst.defend(); System.out.println(String.format("%%s attacked %s: its %s was attacked, and its %s was defended", robotFirst.getName(), robotSecond.getName(), attacked, defended)); } }

You must implement the getName() method in AbstractRobot class. As in the doMove method you are calling the getName() method through AbstractRobot class. But getName() method is implemented in the child class(Robot), however you need to implement the getName() method in the parent class(AbstractRobot class) I'm not posting the exact answer, but I hope you got what Iam saying. Good Luck

I figured it out. The parameter of the doMove method in the Solutions class needed to be Robot NOT AbstractRobot.
