Create An Array Sequence



In [20]:

    
// Create an array that contains arrays with first and last names
val ages = Array(42,25,28,38,58,63,23,458,2569,584,25,25,878)

Elements Less Than 100



In [21]:

    
ages.filter(_ < 100)









    Out[21]:





Array(42, 25, 28, 38, 58, 63, 23, 25, 25)

Elements Greater Than 100



In [22]:

    
ages.filter(_ >= 100)









    Out[22]:





Array(458, 2569, 584, 878)

Elements That Are Even



In [23]:

    
ages.filter(_ % 2 == 0)









    Out[23]:





Array(42, 28, 38, 58, 458, 584, 878)
