首先让我们创建一个带有字符串值的集合 −
Set<String>set = new HashSet<>(Arrays.asList("One", "Two", "Three", "Four", "Five", "Six"));
现在，使用 String.join() − 将其转换为逗号分隔的字符串
String str = String.join(", ", set);
示例
以下是在 Java 中将一组字符串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[]) {
Set<String>set = new HashSet<>(Arrays.asList("One", "Two", "Three", "Four", "Five", "Six"));
System.out.println("Set = " + set);
String str = String.join(", ", set);
System.out.println("Comma separated String: "+ str);
}
}
输出
Set = [Five, Six, One, Four, Two, Three] Comma separated String: Five, Six, One, Four, Two, Three
