Working through in-chapter examples

As you’re working through the chapter, you may want to test some of the example code listings for yourself. Because the code listings in this chapter deal primarily with defining and manipulating data types, testing the examples will involve creating an instance of the class being defined, manipulating that instance using its properties or methods, and then viewing the values of the that instance’s properties. For viewing those values, you’ll want to write values into a text field instance on the Stage, or use the trace() function to print values to the Output panel. These techniques are described in detail in “Testing in-chapter example code listings”.
