Scala – Printing Common Elements from Two Arrays

Here, we will create two arrays of integer elements. Then we will use intersect() method to get the common elements of both arrays.  The intersect() method return an array that contains common elements.

Scala code to print the common elements of two arrays

The source code to print common elements of two arrays is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print common elements of two arrays

object Sample {
  def main(args: Array[String]) {
    var arr1 = Array(1, 2, 3, 4, 5);
    var arr2 = Array(6, 7, 1, 2, 8);
    var arr3 = new Array[Int](5);

    var i: Int = 0;

    arr3 = arr1.intersect(arr2);

    println("Common elements of arrays:");
    while (i < arr3.length) {
      printf("%d ", arr3(i));
      i = i + 1;
    }
    println();
  }
}

Output

Common elements of arrays:
1 2

Explanation

In the above program, we used an object-oriented approach to create the program. We created an object Sample, and we defined main() function. The main() function is the entry point for the program.

In the main() function, we created two array arr1, arr2. Then we used intersect() method to get the common elements of arr1 and arr2. After that, we printed the common elements on the console screen.
