Scala – Find the Second Largest Element of an Array

Here, we will create an array of integer elements, and then we will find the second largest element from an array and print the result on the console screen.

Scala code to find the second largest element from the array

The source code to find the second largest element from the array is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to find the second largest element 
// from the array

object Sample {  
    def main(args: Array[String]) {  
        var IntArray = Array(10,50,40,20,30)
        var count:Int=0
        var large1:Int=0
        var large2:Int=0
        
        large1=IntArray(0)
        while(count<IntArray.size)
        {
            if (large1 < IntArray(count)) 
            {
                large2 = large1
                large1 = IntArray(count)
            }
            else if( large2 < IntArray(count) ) 
            {
                large2 =  IntArray(count);
            }
            count=count+1
        }
        printf("Second largest element is: %d\n",large2)
    }
}  

Output

Second largest element is: 40

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 a array IntArray and three integer variables count, large1, large2. Then we found the second largest element by comparing each array element and then print the result on the console screen.
