Groovy - sharing classes and functions between files

Summary:

Content (required):

is it possible to share classes and methods written in one groovy file (in groovy script) with other groovy script files.

E.g. If I have a file in my calc manager rules folder as follows: GroovyFile1 containing the class and function definitions as follows:

public class Car
{
   String make
   String model
   double mpg
   
   public Car(String v_make, String v_model, double v_mpg)
   {
   		
      make = v_make
      model = v_model
      mpg = v_mpg
   }
   
   
	double costPerMile()
    {
    	return (1.51 * 4.54)/mpg
    }


}

Then suppose I have a second file GroovyFile2 , is it possible to create instances of the class in this file from GroovyFile1 e.g.
