class dig{
   public static void main(String args[]){
       Scanner s=new Scanner(System.in);
       System.out.print("Enter number:");
       int n=s.nextInt(),sum=0,od=0,t=0,r;
       if(n<0){
           n=-n;
       }
       while(n>0){
           r=n%10;
           sum=sum+r;
           t=t+1;
           if(r%2==1){
               od=od+1;
           }
           n=n/10;
       }
       System.out.println();
       System.out.println("Count of digits of number is "+t);
       System.out.println("Count of odd digits of number is "+od);
       System.out.println("Sum of digits of number is "+sum);
   }
}

Output:
