As we know, two lists are equal when they have exactly the same elements and in the exact same order. Soif we care about the order, we can useequals()method for equality check: @Test public void equalityCheckOfTwoLists() { List<Integer> list1 = Arrays.asList(1, 2, 3); List<Integ...

List<Integer> list1 = Arrays.asList(1, 2, 3, 3); List<Integer> list2 = Arrays.asList(3, 1, 3, 2); System.out.println(CollectionUtils.isEqualCollection(list1, list2)); //true 1. 2. 3. 4. 当两个集合包含具有完全相同基数的完全相同元素时,isEqualCollection()方法将返回true。 结论:...
