I'm working on homework and I'm close but I am having an issue. I just learned how to work with packages in eclipse so I have a class that is importing another class from a package (I think I said that right) The main prompts the user to enter an integer between -100 and 100 and I am having an issue with validating it. I know the issue is where I'm importing I'm just unsure the direction I need to go to fix it.

This is a section of my main code. (my issue starts with the last couple lines if you want to skip ahead)

    import myUtils.util.Console;

    public class ConsoleTestApp
    {
         public static void main(String args[])
         {
             // create the Console object
             Console c = new Console();

            // display a welcome message
            c.println("Welcome to the Console Tester application");
            c.println();

            // int
            c.println("Int Test");
            int i = c.getIntWithinRange("Enter an integer between -100 and 100: ", -101, 101);
            c.println();

I have a class called Console that is located in another package that I believe I have properly imported. here is the code I am stuck on in my console class.

    public int getIntWithinRange(String prompt, int min, int max)
{

    int i = 0;
    boolean isValid = false;
    while (isValid == false)
    {
        System.out.println(prompt);
        if (sc.hasNextInt())
        {
            //if user chooses menu option less than 1 the program will print an error message
            i = sc.nextInt();
                if (i < min)
                {
                    System.out.println("Error! Please enter an int greater than -100");
                }

                else if (i > max)
                {
                    System.out.println("Error! Please enter an int less than 100");
                }

                else
                    isValid = true;
        }

        else 
        System.out.println("Error! Invalid number value");
        sc.nextLine();

    }
        // return the int
        return i;

}

when I run this I keep getting my last print which is an invalid number value. am I not importing the code from the main method in the other console properly?
