步骤2:使用Stream API将List转换为LinkedHashSet 在Java 8中,我们可以使用Stream API来处理集合。使用stream()方法获取List的流,并使用collect()方法将流转换为LinkedHashSet。 importjava.util.ArrayList;importjava.util.LinkedHashSet;importjava.util.List;importjava.util.stream.Collectors;publicclassListToLinkedHas...

有序就是怎么存进去,怎么取出来。 用上图的例子就是最常见的hashset的存储和输出,无序的。现在对它进行修改。 只要在开头进行一个小修改就可以了。 顺序是不重要的,唯不唯一很重要,list和set最重要的区别就是唯一性。需要唯一走set集合,无所谓就走list。
