Does Java pass by reference or pass by value? for a deeper exploration of object references. Notice in this code that when we pass the values from one object to the other, two different objects ...

java-object-diff is a simple ... So your call to action: if you need to diff and/or merge collection types like ArrayList, perhaps even with multiple occurence of the same value, please let me know.

Java’s equals() and hashcode() are two methods that work together to verify if two objects have the same value. You can use them to make object comparisons easy and efficient in your Java programs.
