如何使用Scala访问Spark DataFrame中每个单元格的最后两个字符以对其值进行一些计算

import org.apache.spark.sql.functions._
import org.apache.spark.sql.types._

val spark = SparkSession.builder().appName("DataFrameExample").getOrCreate()
val data = Seq(("John Doe", 25), ("Jane Smith", 30), ("Bob Johnson", 35))
val df = spark.createDataFrame(data).toDF("name", "age")

val extractLastTwoChars = udf((str: String) => str.takeRight(2))

val transformedDF = df.withColumn("lastTwoChars", extractLastTwoChars(col("name")))

val resultDF = transformedDF.withColumn("agePlus10", col("age") + 10)
