A table of data types is given below. You will see their uses further. Java’s class libraries define powerful utility classes, such as Date and DateFormat. Since Scala interoperates seamlessly with Java, there is no need to implement equivalent classes in the Scala class library–we can simply import the classes of the corresponding Java packages. The null value is of type scala.Null and is thus compatible with every reference type. It denotes a reference value which refers to a special "null" object. It denotes a reference value which refers to a special "null" object. val df = spark.range1.selectcurrent_date scala> df.show ----- current_date ----- 2017-09-16 ----- scala> df.printSchema root -- current_date: date nullable = false Internally, current_date creates a Column with CurrentDate Catalyst leaf expression.
