Scala program to find the second largest element from the array

Here, we are going to learn how to find the second largest element from the array in Scala programming language?
Submitted by Nidhi, on May 08, 2021

Problem Solution:

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.

Program/Source Code:

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.
