@TTaJTa4 you can use the code belowasan example.Both ways are fine.importjava.util.ArrayList;importjava.util.LinkedHashSet;importjava.util.Set;publicclassConvertLinkedHashSetToArrayList{publicstaticvoidmain(String[]args){Set<String>testStrings=newLinkedHashSet<>();testStrings.add("String 1");...
Example:This is another approach that you can use to get LinkedHashSet from an ArrayList. Here, we are passing ArrayList as an argument to the constructor of LinkedHashSet.import java.util.ArrayList; import java.util.LinkedHashSet; public class Main { public static void main(String[] args)...
LinkedHashSet.toArray(values); System.out.println(Arrays.toString(values)); Program Output. [A, B, C, D, E] 5.3. Convert LinkedHashSet to ArrayList Example Java example to convert a LinkedHashSet to arraylist usingJava 8 stream API. ...
importjava.util.LinkedHashSet;publicclassLinkedHashSetExample{publicstaticvoidmain(String[]args){LinkedHashSet<String>set=newLinkedHashSet<>();// 添加元素set.add("apple");set.add("banana");set.add("orange");// 打印集合System.out.println(set);// 输出结果:[apple, banana, orange]// 判断元...
createAlleles(new ArrayList<Allele>(variantAlleles)); } return sampleVariantAlleles; } Example #6Source File: SDGeneratorManager.java From spring-data-generator with MIT License 6 votes private Set<String> validateExtends(Class<?>[] additionalExtends){ Class<?> extendTemporal; boolean error...
我们首先需要创建一个List对象,并向其添加元素。在这个示例中,我们将创建一个名为list的ArrayList,并向其中添加一些整数。 importjava.util.ArrayList;importjava.util.List;publicclassListToLinkedHashSetExample{publicstaticvoidmain(String[]args){// 创建一个List对象List<Integer>list=newArrayList<>();// 向List...
// Adding new elements to the HashSet daysOfWeek.add("Monday"); daysOfWeek.add("Tuesday"); daysOfWeek.add("Wednesday"); daysOfWeek.add("Thursday"); daysOfWeek.add("Friday"); daysOfWeek.add("Saturday"); daysOfWeek.add("Sunday"); // Adding duplicate elements will be ignored ...
importjava.util.LinkedHashSet;publicclassLinkHashSetExample {publicstaticvoidmain(String[] args) { LinkedHashSet linkedHashSet=newLinkedHashSet(); linkedHashSet.add("d"); linkedHashSet.add("a"); linkedHashSet.add("c"); linkedHashSet.add(3); ...
并且失去了元素的插入顺序信息,也就是说使用 Iterator 遍历 HashSet 得到的结果是不确定的。允许null元素LinkedHashSet:具有HashSet的查找效率,且内部使用双向链表维护元素的插入顺序。 List ArrayList:基于动态数组实现,支持随机访问。 Vector:和ArrayList 类似,但它是线程...
