콘솔에서 돌렸더니
Set에서 filter()를 사용하여 해당 문자("blogspot")를 포함하는 값을 모은다(Set은 immutable Set).
val feeds1 = Set("blog.toolshed.com", "pragdave.pragprog.com",
"pragmactic-osxer.blogspot.com", "vita-contemplative.blogspot.com")
val feeds2 = Set("blog.toolshed.com", "martinfowler.com/bliki")
val blogspotFeeds = feeds1 filter ( _ contains "blogspot")
println("blogspot Feed : " + blogspotFeeds.mkString(", "))
"pragmactic-osxer.blogspot.com", "vita-contemplative.blogspot.com")
val feeds2 = Set("blog.toolshed.com", "martinfowler.com/bliki")
val blogspotFeeds = feeds1 filter ( _ contains "blogspot")
println("blogspot Feed : " + blogspotFeeds.mkString(", "))
