Scala program to sort an array in descending order using selection sort

Program/Source Code:

The source code to sort an array in descending order using selection sort is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to sort an array in descending order 
// using selection sort

object Sample {  
    def main(args: Array[String]) {  
        var IntArray = Array(11,15,12,14,13)
        var i:Int=0
        var j:Int=0
        var t:Int=0
        
        var max:Int=0
        
        //Sort array in descending order using selection sort.
        while(i<5)
        {
            max=i;
            
            j=i+1
            while(j<5)
            {
                if(IntArray(j)>IntArray(max))
                    max=j;
                j=j+1;
            }
            
            t=IntArray(i);
            IntArray(i)=IntArray(max);
            IntArray(max)=t;
            
            i=i+1;
        }
        
        i=0;
        println("Sorted Array in descending order: ");
        while(i<5)
        {
            printf("%d ",IntArray(i));
            i=i+1;
        }
        println()
    }
}

Output:

Sorted Array in descending order: 
15 14 13 12 11 

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 an array IntArray that contains 5 integer items. Then we sorted the created array in descending order using selection sort. After that, we printed the sorted array on the console screen.
