Best Fare Calculator

Hi All,

I’m currently working on building the “Best Fare Calculator” project and I’m positivie the code I’ve written is incorrect. Also, the compiler tells me so. I want to know exactly what my mistakes are, but of course, there is nothing to help me view it. Does anyone have an idea where I can at least get a little help correcting my mistakes?

Thanks

Hey @dscntr17!

To help you, we need your code and a link to the exercise. Once you provide that, we can help you find a solution.

import java.util.Arrays;

public class TransitCalculator() {
  
  public TransitCalculator() {
    String [] rides = {"Pay-per-ride", "7-day unlm", "30-day unlm"};
    double [] prices = {2.75, 33.00, 127.00};
  }
  
  public double unlimited7Price() {
    if(prices[1] * 3 / 20 ) {
      return 4.95;
    }
    else if(prices[1] * 4 / 50) {
      return 2.64;
    }
    else(prices[1] * 1 / 14) {
      return 2.36;
    }
    
  }
  
  public double getRidePrices() {
    if(prices[0] % 1) {
      return 2.75;
    }
    else if(prices[1] % 7) {
      return 4.71;
    }
    else(prices[2] % 30) {
      return 4.23;
    }
  }
  
  public String getBestFare(){
    for(double prices : String getRidePrices) {
      return "You should get the 30-day Unlimited option at 4.23 per ride.";
    }
  }
  
  public static void main(String[] args) {
     
  }
}

So, basically I need to determine the correct fare option for transit riders. I know there’s no code in my main, which is probably one of the reasons why I’m not getting a correct output. But other than that, I’m stuck.

And I don’t know why the code didnt indent when I copied this over.

Hey,

Your code didn’t indent because you didn’t surround it with backticks… checkout this topic to see how to properly format your code:

And could you please send the link to the exercise?

Hello, @dscntr17.

Question for you. What condition(s) are you testing in your if statements? They are all similar to this:

if(prices[1] * 3 / 20 )

When we evaluate the expression that is being tested for truthiness we have:

if(33.00 * 3 / 20)

So, the entire if is:

if(4.95) {
  return 4.95;
}

I’m unsure where you are going with these. It seems you may have misinterpreted the instructions, and may need to go back and review the suggested prerequisites:

Ok, I see where I went wrong on that method. I will go back and re-read my notes. And yes, I may not have understood the directions entirely. I’m very new to this course, so I’m not confindent in the coding I do.

Thanks for your help.

You’re welcome. There’s no shame in going back to review things we’ve learned. I have to do it all the time. Keep at it, and you’ll get it. :+1:
