在 Java 中将字符串转换为逗号分隔的 List（列表）
首先，设置一个具有字符串值的列表-
List<String> myList = new ArrayList<>(
Arrays.asList("One", "Two", "Three", "Four"));现在，使用String.join()将它们设置为逗号分隔的列表-
String str = String.join(", ", myList);示例
以下是在Java中将字符串转换为逗号分隔列表的程序-
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
