Question about the task

Resolved

can you please tell me where I'm going wrong and what have I forgotten? Please be clear as this is the first time I'm trying to learn programming language, thanks.

Write code for the convertEurToUsd method, which converts euros to dollars at a given exchange rate.
Use a return statement to return the result from the convertEurToUsd method. Example: return 123*435;
Call the convertEurToUsd method twice in the main method with any arguments.
Display the results, each time on a new line.

Hint:
The result is calculated using the following formula: US dollars = euros * exchange rate

Requirements:

The convertEurToUsd method must multiply the euro amount by the exchange rate and return the result.
The main method must call the convertEurToUsd method twice with any arguments.
The main method should display the result of the calls, each time on a new line.
The convertEurToUsd method should not display anything.

package com.codegym.task.task03.task0303; /* Currency exchange */ public class Solution { public static void main(String[] args) { System.out.println(convertEurToUsd(Usd)); System.out.println(convertEurToUsd(Usd));//write your code here } public static double convertEurToUsd(int eur, double exchangeRate){ int eur = 100; double exchangeRate = 1.2; Usd = eur * exchangeRate; return Usd; //write your code here } }

In method public static double convertEurToUsd(int eur, double exchangeRate) you have return double convertEurToUsd, not usd

convertEurToUsd() is a method. Usd is a value that is returned by this method.

You aren't supposed to set exchangeRate or eur equal to anything. Those variables will be set to some value when the method is called. All you need to do is write the formula the will return the proper converted number.

Look at the example

public class Solution {
    public static void main(String[] args) {
        System.out.println(add(3, 5.2));
    }

    public static double add(int firstNumber, double secondNumber){
        double sum = firstNumber + secondNumber;
        return sum;
    }
}
