Scala program to find the prime numbers from the array

Program/Source Code:

The source code to print prime numbers from the array is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print prime numbers from array

import scala.util.control.Breaks._    

object Sample {  
def main(args: Array[String]) {
        var IntArray = Array(11,12,13,14,15)
        
        var i:Int=0
        var j:Int=0
        var flag:Int=0
        
        println("Prime Numbers are:");
        while(i<IntArray.size)
        {
            flag = 0
            j=2
            
            breakable
            {
                while(j<IntArray(i)/2)
                {
                    if(IntArray(i)%j==0)
                    {
                        flag=1
                    }
                    j=j+1
                }
            }
            if(flag == 0)
                printf("%d ", IntArray(i))
            i=i+1		
        }
        println()
    }
}  

Output:

Prime Numbers are:
11 13

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 integer array IntArray with 5 elements. Then we found the prime numbers from the array and printed them on the console screen.
