We have set the age field of the first Person object to 20 and the age field of the second Person object to 22. We have created a RecursiveComparisonConfiguration object with the withIgnoredFields() method and passed the age field name to it. We have created a RecursiveComparisonDifferenceCalculator object with the RecursiveComparisonConfiguration object as an argument. We have called the compareArrays
