[Java 8 – How to check if two lists are equal](
System.out.println(CollectionUtils.isEqualCollection(list1, list2));//true TheisEqualCollection()method returns true when the two collections contain exact same elements with exactly the same cardinalities. Conclusion: In this tutorial, we learned to check if two lists are equals in Java. We now...
return true; } //Only one of them is null else if(list1 == null || list2 == null) { return false; } else if(list1.size() != list2.size()) { return false; } //copying to avoid rearranging original lists list1 = new ArrayList<T>(list1); list2 = new ArrayList<T>(list2...
static boolean compareListsIgnoringOrder(ArrayList list1, ArrayList list2) { if (list1 == null || list2 == null) return false; if (list1.size() != list2.size()) return false; for (Object o : list1) { list2.remove(o); } if (list2.size() != 0) return false; return true;...
Note that the difference between two lists is equal to a third list which contains either additional elements or missing elements. 1. Comparing Two Lists for Equality 1.1. Sort then Compare The following Java program tests if two given lists are equal. To test equality, we need to sort both...
Description: The IS NULL expression can be used to check whether a relationship has been set between two entities. In this case, the query checks whether the teams are associated with any leagues and returns the teams that do not have a league. See also: NULL Comparison Expressions and NULL...
The general contract for the Object.equals method states that equals must be symmetric (in other words, a.equals(b) if and only if b.equals(a)). The contracts for List.equals and Set.equals state that lists are only equal to other lists, and sets to other sets. Thus, a custom equal...
and all corresponding pairs of elements in the two lists areequal. (Two elementse1ande2areequalifObjects.equals(e1, e2).) In other words, two lists are defined to be equal if they contain the same elements in the same order. This definition ensures that the equals method works properly ac...
