Java - compilation error - cannot find symbol - variable Terminal

Question

I have just started learning Java for first time. I have an issue when compiling the following code.

public class Conversion {
public static void main (String[] args) {

    double euros;
    double dollars;
    System.out.println("Sum in euros? ");
    euros = Terminal.lireDouble();
    dollars = euros * 1.118;
    System.out.println("Sum in dollars: ");
    System.out.println(dollars);
}

}

I get the following error message:

/Users/Mathieu/IdeaProjects/Conversion/src/com/company/Conversion.java:9:17 java: cannot find symbol symbol: variable Terminal location: class com.company.Conversion

Please, could you help me ? What is wrong with my code.

Thank you in advance

What is supposed to be read in Java like cin (c++) or scanf (in C) or Console.ReadLine() (in c#) ? — Mathieu Seligmann, Oct 17 '20 at 07:22
Well the compiler doesn't know what it means either. Maybe your professor notebook contains some more information somewhere about importing `Terminal` before you use it. — khelwood, Oct 17 '20 at 07:22
*What is supposed to be read in Java like cin (c++) or scanf (in C) or Console.ReadLine() (in c#) ?* ... read about `System.in` and the `Scanner` class. — Stephen C, Oct 17 '20 at 07:25

In order to get input from the user use this

    import java.util.Scanner;
    public class Conversion {
    public static void main (String[] args) {
        Scanner in = new Scanner(System.in);
        double euros;
        double dollars;
        System.out.println("Sum in euros? ");
        euros = in.nextDouble();
        dollars = euros * 1.118;
        System.out.println("Sum in dollars: ");
        System.out.println(dollars);
    }
   }

Scanner is used to get input from the user
