在 Java 中将 List 转换为 Set

假设以下是带有字符串值的列表-

List<String> list = Arrays.asList("Jacob", "Kiya", "Bradley", "Tom", "Jamie");

现在，将上面的列表转换为set-

Set<String> set = new HashSet<String>(list);

示例

以下是在Java中将List转换为Set的程序-

import java.util.*; import java.util.stream.*; public class Demo { public static void main(String args[]) { List<String> list = Arrays.asList("Jacob", "Kiya", "Bradley", "Tom", "Jamie"); System.out.println("List = " + list); Set<String> set = new HashSet<String>(list); System.out.println("Set (converted from list) = " + set); } }

输出结果

List = [Jacob, Kiya, Bradley, Tom, Jamie] Set (converted from list) = [Jamie, Tom, Bradley, Kiya, Jacob]
