what I'm doing wrong?

Question about the task

Climb, fly, and run

Java Core, Level 2, Lesson 12

Resolved

does anyone know what I'm going wrong? or what I'm ignoring?

1. In the Solution class, make a public CanFly interface with a void fly() method.
2. In the Solution class, make a public CanClimb interface with a void climb() method.
3. In the Solution class, make a public CanRun interface with a void run() method.
4. Use common sense to decide which interfaces you need to add to each class.
5. Add interfaces to the Cat, Dog, Tiger, and Duck classes.

Requirements:

The Solution class must have a CanFly interface with a void fly() method.
The Solution class must have a CanClimb interface with a void climb() method.
The Solution class must have a CanRun interface with a void run() method.
A Cat object must be able to run (support the CanRun interface) and climb trees (support the CanClimb interface).
A Dog object must be able to run (support the CanRun interface).
The Tiger class must be a Cat.
A Duck object must be able to run (support the CanRun interface) and fly (support the CanFly interface).

package com.codegym.task.task12.task1226; /* Climb, fly, and run */ public class Solution { public static void main(String[] args) { } public interface CanClimb { public void climb(); } public interface CanFly { public void fly(); } public interface CanRun { public void run(); } public class Cat implements CanClimb, CanRun { public void climb(); public void run(); } public class Dog implements CanRun { public void run(); } public class Tiger extends Cat { public void climb(); public void run(); } public class Duck implements CanRun, CanFly { public void fly(); public void run(); } }

Methods in non abstract classes have bodies. Even empty. But have curly brackets. { body } If a class inherits another class you don't need to repeat methods from base class.
