Scala Programming: Find the common elements between two arrays of integers

Scala Programming Array Exercise-15 with Solution

Write a Scala program to find the common elements between two arrays of integers.

Sample Solution:

Scala Code:

object Scala_Array {   
   def main(args: Array[String]): Unit = {     
     var nums1 = Array(2,4,5,7,9) 
     var nums2 = Array(2,3,5,6,9) 
     //Call the following Java class for some array operation
     import java.util.Arrays; 
     println("Original Array1 : "+Arrays.toString(nums1));
     println("Original Array2 : "+Arrays.toString(nums2));     
     println("Common elements of the said two arrays:")
     var i = 0
     var j =0;
        for (i <- 0 to nums1.length-1)
        {
          j=0
          for (j <- 0 to nums2.length-1)
            {
                if(nums1(i) == nums2(j))
                {
                  print(s"${nums1(i)}, ")        
                 }
            }
         }
    }
 }

Sample Output:

Original Array1 : [2, 4, 5, 7, 9]
Original Array2 : [2, 3, 5, 6, 9]
Common elements of the said two arrays:
2, 5, 9,
