 {


    public  brainly


              static


                  =void main


 (String[] args)

   {


         Scanner scanner = new Scanner



(System.in); int i =0; int num =0



; //Empty String String primeNumbers = "



"; System.out.println("Enter the value of n:");



       int n = scanner.nextInt(); scanner.close();



      for (i = 1; i <= n; i++) { int counter=0; for


(


num =i; num>=1; num--)

         {


     if(i%num==0)

     {


  counter = counter + 1;


     }

  }


  if (counter ==2)

  {


     //Appended the Prime number to the String primeNumbers = primeNumbers + i + " ";



   }


        }



       System.out.println



("Prime numbers from 1 to n are :")






; System.out.println(primeNumbers); } }
