   int vowels = 0; 
   char chh,ch;

   char[10] a = sc.next().toCharArray(); 

   for(int i=0;i<a.length;i++) 
 {
    chh=a[i]; 
    System.out.print(a[i]); 
    if(chh >='A' && chh <='Z') 
       uppercase++; 
    ch=Character.toUpperCase(chh); 
    if (ch='A' || ch-'E' || ch-'I' || ch='O' || ch='U')
