Programming Groovy 2

10.3 Using Groovy Classes from Groovy

To use a Groovy class from within our Groovy code, we only have to make sure the Groovy class is in our ​classpath​. We can use the Groovy source code as is, or we can compile it into a ​.class​ file and use it—it’s our choice. When our Groovy code references a Groovy class, Groovy looks for the ​.groovy​ file with the name of the class in our ​classpath​; if it does not find it, it looks for a ​.class​ file with the same name.

Suppose we have Groovy source code ​Car.groovy​, shown here, in a directory named ​src​:

class Car
{
  int year = 2008
  int miles

  String toString() { "Car: year: $year, miles: $miles" }
}
