在上面的示例中,我们首先创建了两个List对象list1和list2,并向它们添加了相同的元素。然后,我们定义了一个compareLists方法,用来比较这两个List是否具有相同的值。最后,在main方法中调用compareLists方法,并输出比较结果。 类图 CompareLists+boolean compareLists(List list1, List list2)List 在类图中,我们定义了一...
下面是一个使用Set数据结构判断两个List是否存在重复项的示例代码: importjava.util.ArrayList;importjava.util.HashSet;importjava.util.List;importjava.util.Set;publicclassCompareTwoLists{publicstaticbooleanhasDuplicate(List<Integer>list1,List<Integer>list2){Set<Integer>set1=newHashSet<>(list1);Set<Intege...
To compare two lists in Java, you can use the equals() method of the List interface. The equals() method compares the elements of the two lists and returns true if the lists are equal, and false if they are not. Here is an example of how to compare two lists in Java: List<String...
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 ...
I would like to compare two ComplexClazzs for equality independent of the ordering in the lists. In my legacy code this is so far solved with ReflectionAssert.assertReflectionEquals(expectedResult, actualResult, ReflectionComparatorMode.LENIENT_ORDER); but I would like to get rid of the ...
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: ...
不过,apache commons collectionutils类通过intersection和subtract方法提供了以下功能:
