Tokenize a string: Difference between revisions

Separate the string "Hello,How,Are,You,Today" by commas into an array so that each index of the array stores a different word. Display the words to the 'user', in the simplest manner possible, separated by a period. To simplify, you may display a trailing period.

s" Hello,How,Are,You,Today" s" ," split .tokens \ Hello.How.Are.You.Today

println 'Hello,How,Are,You,Today'.split(',').join('.')
