Question about the task

Implement the fight method

Java Syntax, Level 5, Lesson 5

Under discussion

how to realize 6th requirement.

Implement the boolean fight(Cat anotherCat) method:
implement a mechanism for cats to fight based on their weight, age and strength.
You can decide for yourself how a cat's characteristics factor into combat.
The method should determine whether we (this) won the fight, i.e. return true if we won and false if not.

The following condition must be met:
if cat1.fight(cat2) returns true,
then cat2.fight(cat1) must return false

Requirements:

The Cat class must have a constructor with no parameters.
The Cat class must contain public fields age, weight, and strength.
The Cat class must have a fight method.
In the fight method, implement a mechanism for cats to fight based on their weight, age and strength.
The method should return the same value every time we fight the same cat.
If cat1 beats cat2, then cat2 must lose to cat1.

package com.codegym.task.task05.task0502; /* Implement the fight method */ import java.io.*; public class Cat { public int age; public int weight; public int strength; public Cat() { } public boolean fight(Cat anotherCat) { if(this.strength>strength||this.age<age||this.weight>weight) { return true; } else if(this.strength == strength&&this.age==age&&this.weight == weight) { if(fight(this)== false) return true; else return false; } else return false; } public static void main(String[] args) { Cat cat1 = new Cat(); cat1.age =2; cat1.weight = 25; cat1.strength = 12; Cat cat2 = new Cat(); cat2.age =2; cat2.weight = 25; cat2.strength = 12; Cat cat3 = new Cat(); cat3.age = 3; cat3.weight = 15; cat3.strength = 5; cat1.fight(cat2); cat1.fight(cat3); cat2.fight(cat1); } }

My solution was this: Each cat has 3 parameters (age, strength and weight). If you write a condition that requires 2 out of 3 of these parameters to be superior to win then you don't need to come up with a specific solution to satisfy 6th requirement. Because if cat1 is superior in 2 parameters out of 3 to cat2 (the if condition was satisfied and the result was returned as true), then cat2 automatically cannot be superior to cat1 in 2 parameters as well (we've discovered that it's weaker in 2, and the total is 3 which leaves us with only max 1 of superior parameters) and when we swap roles the if condition will not be satisfied this time and the result will be returned as false. idk how clear my explanation is, I tried =)

try following code:

Cat cat1 = new Cat();
        cat1.age =3;
        cat1.weight = 25;
        cat1.strength = 12;

        Cat cat2 = new Cat();
        cat2.age =2;
        cat2.weight = 20;
        cat2.strength = 10;
        System.out.println(cat1.fight(cat2));
        System.out.println(cat2.fight(cat1));

and fight method should be like this:

public boolean fight(Cat anotherCat) {
        //write your code here
        if(this.age>anotherCat.age && this.weight>anotherCat.weight && this.strength>anotherCat.strength)
        {
            return true;
        }
        else
        {
        return false;
        }

    }

Not sure if this is what you are asking: If Cat1 fights Cat2 and wins then Cat2 will always loose. Meaning, if Cat1.fight(Cat2) returns true then Cat2.fight(Cat1) should return false. You don't need Cat3 by the way. Test your code for a lot of different values for cat1 and cat2. Under any condition, the result of Cat1.fight(Cat2) should be opposite of Cat2.fight(Cat1) Also, I did not understand what you have done in Line 28. You are trying to recursion here? Why?
