---
You are recreating instances of your `Attacker` class and the problem with that is the `low` value is associated with only that specific instance. So when you create a new one after the fact in `Defender`, you lose the value. I've also separated `Attacker` and `Defender` c... | To pass a value into another class you will need to pass it as a parameter either of the other class's constructor or a setter method.
So if you give Attacker a `setLow(int low)` method, you can pass in the information.
```
public void setLow(int low) {
this.low = low;
}
```
And then call the method when needed. |
