Java 中将 ArrayList 转换为 LinkedList 的程序
假设以下为我们的 ArrayList −
List<String> arrList = Arrays.asList("John", "Jacob", "Kevin", "Katie", "Nathan");
现在使用 toCollection() 将此 ArrayList 转换为 LinkedList −
List<String> myList = arrList.stream().collect(Collectors.toCollection(LinkedList::new));
示例
以下是在 Java 中将 ArrayList 转换为 LinkedList 的程序 −
import java.util.*; import java.util.stream.*; public class Demo { public static void main(String args[]) { List<String> arrList = Arrays.asList("John", "Jacob", "Kevin", "Katie", "Nathan"); System.out.println("ArrayList = " + arrList); List<String> myList = arrList.stream().collect(Collectors.toCollection(LinkedList::new)); System.out.println("LinkedList (ArrayList to LinkedList) = " + myList); } }
输出
ArrayList = [John, Jacob, Kevin, Katie, Nathan] LinkedList (ArrayList to LinkedList) = [John, Jacob, Kevin, Katie, Nathan]
