如何在Kotlin中将hashmap转换为csv文件

import java.io.File
import java.io.FileWriter
import java.io.IOException

fun convertHashMapToCSV(hashMap: HashMap<String, String>, filePath: String) {
    try {
        val fileWriter = FileWriter(filePath)
        
        // 写入CSV文件的表头
        fileWriter.append("Key,Value\n")
        
        // 遍历HashMap并将键值对写入CSV文件
        for ((key, value) in hashMap) {
            fileWriter.append("$key,$value\n")
        }
        
        fileWriter.flush()
        fileWriter.close()
        
        println("HashMap已成功转换为CSV文件。")
    } catch (e: IOException) {
        e.printStackTrace()
    }
}

fun main() {
    val hashMap = HashMap<String, String>()
    hashMap["Name"] = "John"
    hashMap["Age"] = "25"
    hashMap["Country"] = "USA"
    
    val filePath = "path/to/output.csv"
    
    convertHashMapToCSV(hashMap, filePath)
}
