在 Java 中将字符串列表转换为逗号分隔的字符串
java 8object oriented programmingprogramming
首先,假设以下是我们的字符串列表 −
List<String> myList = new ArrayList<>(Arrays.asList("One", "Two", "Three", "Four"));
现在,使用 String.join() 将其转换为逗号分隔的字符串
String str = String.join(", ", myList);
示例
以下是 Java 中将字符串列表转换为逗号分隔的字符串的程序 −
import java.util.*; public class Demo { public static void main(String args[]) { List<String> myList = new ArrayList<>(Arrays.asList("One", "Two", "Three>, "Four")); System.out.println("List = " + myList); // 逗号分隔 String str = String.join(", ", myList); System.out.println("String (Comma Separated) = " + str); } }
输出
List = [One, Two, Three, Four] Comma separated String: One, Two, Three, Four
