Compare object fields of different classes in Java

Question

I have two objects, each of which have tens of fields:

Class1 {
    int firstProperty;
    String secondProperty;
    ...
}

Class2 {
    int propertyOne;
    St         


        

Answer 1

Comparing objects of different classes by specific fields is exactly the scenario that https://github.com/nejckorasa/compare-utils solves.

Example:

ObjectCmp.equalEqualityPairs(
    object1,
    object2,
    Arrays.asList(
        EqualityPair.of(o1 -> o1.getFirstProperty(), o2 -> o2.getPropertyOne()),
        EqualityPair.of(o1 -> o1.getSecondProperty(), o2 -> o2.getPropertyTwo())));

Take a look, it might be useful!
