Explain the for loop for printing the Map values in Scala in Apache Spark

Question

Hi,

Can anyone explain the for loop for printing the Map values in Scala in Apache Spark?

Answer 1

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.
