Hey,

You can see this following code to print the key and values in Map:

for((key,value) <- colors) {
println(key)
println(value)
}

The iteration variable returns a tuple which is being assigned to two variables "key" and "value".

I hope it is clear.

To know more about Spark Scala, It's recommended to join Apache Spark training online today.

Thanks!!
