如何在Apache Spark Java中将dataset数组类型转换为string类型

import org.apache.spark.sql.Dataset;
import org.apache.spark.sql.Row;
import org.apache.spark.sql.SparkSession;

SparkSession spark = SparkSession.builder()
        .appName("Array to String Conversion")
        .master("local")
        .getOrCreate();

String[] array = {"Hello", "World", "Spark"};
Dataset<String> dataset = spark.createDataset(Arrays.asList(array), Encoders.STRING());

import static org.apache.spark.sql.functions.*;

Dataset<Row> result = dataset.select(concat_ws(",", dataset.col("value")).alias("string"));

String resultString = result.first().getString(0);

import org.apache.spark.sql.Dataset;
import org.apache.spark.sql.Row;
import org.apache.spark.sql.SparkSession;
import org.apache.spark.sql.Encoders;

import java.util.Arrays;

public class ArrayToStringConversion {
    public static void main(String[] args) {
        SparkSession spark = SparkSession.builder()
                .appName("Array to String Conversion")
                .master("local")
                .getOrCreate();

        String[] array = {"Hello", "World", "Spark"};
        Dataset<String> dataset = spark.createDataset(Arrays.asList(array), Encoders.STRING());

        Dataset<Row> result = dataset.select(concat_ws(",", dataset.col("value")).alias("string"));

        String resultString = result.first().getString(0);
        System.out.println(resultString);
    }
}
