在Java中将字符串列表转换为逗号分隔的字符串

首先，让我们说以下是我们的String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

以下是在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); } }

输出结果

List = [One, Two, Three, Four] Comma separated String: One, Two, Three, Four
