Not able to fix this

Question about the task

Under discussion

package com.codegym.task.task14.task1409; public class Solution { public static void main(String[] args) { println(new WaterBridge()); println(new SuspensionBridge()); //println(new SuspensionBridge()); //println(new SuspensionBridge()); } public static void println(Bridge bridge){ if (bridge instanceof WaterBridge){ int n=new WaterBridge().GetsCarsCount(); System.out.println(n); } else{ int k=new SuspensionBridge().GetsCarsCount(); System.out.println(k); } } }

1. Create a Bridge interface with an int getCarsCount() method.
2. Write WaterBridge and SuspensionBridge classes that implement the Bridge interface.
3. The getCarsCount() method must return any constant int value.
4. The getCarsCount() method must return different values for different classes.
5. Create a public println(Bridge bridge) method in the Solution class.
6. In the println method, display the result of calling getCarsCount() method on the bridge object.
7. Each class and interface must be in separate files.

Requirements:

The Bridge interface must be in a separate file.
The WaterBridge and SuspensionBridge classes must be in separate files.
The WaterBridge and SuspensionBridge classes must implement the Bridge interface.
The getCarsCount() method must return different int values for different classes, but always the same value for different objects of the same class.
The Solution class must implement a public println method with one Bridge parameter.
The println method must display the number of cars (result of the getCarsCount method) for the passed Bridge object.
The Bridge interface must define an int GetCarsCount() method.

getCarsCount vs GetsCarsCount --- typo in method naming

You also need to create constant variables for your two bridge classes example:

public interface Bridge {
    // const int variables
    int WATER_NUMBER = 0;
    int SUS_NUMBER = 1;

    // methods
    int getCarsCount();
}

on the left pannel, you right click the task folder and then "new", then class or interface etc. then it just does it for you

#1 the method getCarsCount() is mispelled #2 You dont need to test and create new objects, just use bridge.getCarCount() in the print method
