Basic I/O Operations and using Scala Collections APIs

As part of this topic, we will explore Basic I/O operations

• Read data from files
• Convert into collection
• Perform collection operation to preview the data
• Run map-reduce operations

Reading data from files

• To read files from a file system in scala there is a package called scala.io

• Important operations in Source package are as follows
