Create Two Vectors



In [4]:

    
// Create two vectors
val ages = Vector(23,42,12,34)
val lastName = Vector("Jackson", "Dillan", "Bower", "Stein")

Sort Alphabetically



In [5]:

    
// View the sequence alphabetically
lastName.sorted









    Out[5]:





Vector(Bower, Dillan, Jackson, Stein)

Sort Ascending



In [6]:

    
// View the sequence in ascending order
ages.sorted









    Out[6]:





Vector(12, 23, 34, 42)

Sort Descending



In [7]:

    
// View the sequence sorted using i > j
ages.sortWith(_ > _)









    Out[7]:





Vector(42, 34, 23, 12)

Sort By Length



In [8]:

    
// Voew the sequence sorted by descending length
lastName.sortWith(_.length > _.length)









    Out[8]:





Vector(Jackson, Dillan, Bower, Stein)
