where did i go wrong

Question about the task

Currency exchange

Java Syntax, Level 3, Lesson 3

Under discussion

can anyone tell me where i went wrong

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(100,91)); System.out.println(convertEurToUsd(100,91)); } public static double convertEurToUsd(int eur, double exchangeRate) { exchangeRate = 91; double usd = eur * 100; return (usd); } }

You don't need line 16 and line 17 should be:

double usd = eur * exchangeRate;

This is because in the method signature (line 15), "(int eur, double exchangeRate)" already defines the arguments that can be passed to this method i.e. whenever we call the method (lines 10 and 12) we pass an int and a double to this method and then the method's code will be executed on those variables.
