Clarification of a specific method

On my homework I have a question/part where I am confused at (can't understand it).

Iv ) The main method calls the printdata() method for each Earthquake object. The printData() method accepts an Earthquake object as a parameter and prints all the Earthquake's idea, including latitude, longitude, magnitude and classification. Remember that you will need to call the determineClassification() method for the Earthquake object before calling the accessor method and printing the classification.

I understood everything up till the bolded era, what does it mean when it says call the determine method for earthquake object before calling accessor method and printing it.

Part I: earthquake service class has 4 attributes, lat, lon, mag, classification

include following for part I, constructor, second constructor with parameter (lat, lon, mag), accessor for method for each attribute, mutator method for all attributes EXCEPT for classification.

A method named determineclassification() that uses range checking, based on the table shown above and the value of the magnitude attribute, and sets the value of the classification attribute to the appropriate word specified in the table. Remember to choose either low end or high end range checking when designing this method.

Part II italicized.

PSEUDO CODE.
