映射以将String值添加到Java中的每个元素
假设以下是我们的字符串列表-
List list = Arrays.asList("Football", "Basketball", "Hockey", "Cricket","Fencing");现在，映射以将字符串添加到每个元素-
List str = list.stream().map(name -> "Sports " + name + " Outdoor") .collect(Collectors.toList());
上面，我们在每个元素中添加了“运动”和“室外”字符串。
以下是Map的示例，并将字符串值添加到Java中的每个元素-
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);
}
}输出结果
[Sports Football Outdoor, Sports Basketball Outdoor, Sports Hockey Outdoor, Sports Cricket Outdoor, Sports Fencing Outdoor]
