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]
