If you need to compare two lists of objects and want to perform a deep comparison, you can implement a custom method that iterates over the elements of the lists and compares them recursively. This approach allows you to compare complex objects within the lists. Code Example importjava.util....
I have two lists. They contain objects of different types, but both types contain id and name, and id is what I am comparing on. List one is fetched from DB, and list two is sent from frontend. What I need to do is loop through them and find which list item is newly added and ...
此接口对实现它的每个类的对象强加一个默认排序。这种排序被称为类的自然排序,类的compareTo方法被称为其自然比较方法。 Lists (and arrays) of objects that implement this interface can be sorted automatically byCollections.sort(andArrays.sort).
1.1. Sort then Compare The following Java program tests if two given lists are equal. To test equality, we need to sort both lists and compare both lists usingequals()method. TheList.equals()method returnstruefor two list instances if and only if: ...

This interface imposes a total ordering on the objects of each class that implements it. This ordering is referred to as the class's natural ordering, and the class's compareTo method is referred to as its natural comparison method. Lists (and arrays) of objects that implement ...
