在 Java 中将字符串转换为逗号分隔的列表
java 8object oriented programmingprogramming
首先，设置一个包含字符串值的列表 −
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 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
List = [One, Two, Three, Four] Comma separated String: One, Two, Three, Four
