public class Lab7 {

   public static void main(String[] args) {
       Scanner scan=new Scanner(System.in);
       System.out.println("Enter a String or type "quit" to exit:");
       String line=scan.nextLine();
      
       line=line.toLowerCase();
       while(line.equals("quit")==false)
       {
           //counter is used to count the number of vowels
           int counter =0;
           for(int i=0;i<line.length();i++)
           {
               if(line.charAt(i)=='a' ||
                       line.charAt(i)=='e'||
                       line.charAt(i)=='i'||
                       line.charAt(i)=='o'||
                       line.charAt(i)=='u')
               {
                   counter++;
               }
           }
           System.out.println("the String "+line+" contains "+counter+ " vowels(s)");
           System.out.println("Enter a String or type "quit" to exit:");
           line=scan.nextLine();
          
           line=line.toLowerCase();
       }
