使用Set可以快速去除重复的元素并提高查找的效率。 privatestaticbooleancheckForDuplicates(List<String>list1,List<String>list2){// 将list1转换为SetSet<String>set1=newHashSet<>(list1);// 将list2转换为SetSet<String>set2=newHashSet<>(list2);// 接下来将会检查是否有交集// ...} 1. 2. 3. 4...
在这个判断重复值的情况下,设计一个简单的类来封装逻辑也是一个好主意。 ListChecker+list my_list+set unique_values+check_duplicates() : void+add_value(value) : void 这个类ListChecker负责检查一个列表中的重复值,实现一个check_duplicates方法来执行这一检查,并定义一个add_value方法用于添加值到集合中。
