映射到将字符串值添加到 Java 中每个元素
假设我们的 String List 如下所示 −
List list = Arrays.asList("Football", "Basketball", "Hockey", "Cricket","Fencing");
现在映射到每个元素以添加字符串 −
List str = list.stream().map(name -> "Sports " + name + " Outdoor") .collect(Collectors.toList());
上面,我们已经向每个元素添加了“Sports”和“Outdoor”字符串。
以下是映射和在 Java 中向每个元素添加字符串值的一个示例 −
示例
import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; public class Demo { public static void main(String[] args) { List list = Arrays.asList("Football", "Basketball", "Hockey", "Cricket","Fencing"); List str = list.stream().map(name -> "Sports " + name + " Outdoor") .collect(Collectors.toList()); System.out.println(str); } }
输出
[Sports Football Outdoor, Sports Basketball Outdoor, Sports Hockey Outdoor, Sports Cricket Outdoor, Sports Fencing Outdoor]
