Before You Begin

Before you create your custom comparators, take into account the following requirements for the comparators.

• Determine how many comparators you need to create and whether each will require a different Java class or some can use the same Java class.

• Determine what parameters, if any, you need to define for each comparator.

• Determine what validations, if any, need to be created.

• Determine whether you need to use a data source.

• Decide if the comparators you create will have a dependency on any other comparator classes.

• Decide whether you will use curve adjustment, linear fitting, or neither.
