Question

im working a search method on a linked list this my code

Node item=head;
 String help=item.getKonten();
 System.out.printf("data to search");
    search=input.nextLine();

    while (help.compareTo(search)>0){
        if (help.equals(search)){
            System.out.println ("index " + index);
            ktemu=1;
        } else {
            item=item.getLink();
            bantu1=item.getKonten();        
        }
        index++;
    }

    if (ktemu == 0){
         System.out.println("data not found");
    }

the output
data : 1,2,3,4,5
data to search 2
data not found
anyone can point me whre this code goes wrong so the index not shown up

Answer 1

compareTo method returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

So when you compare 1 with 2 which return negative value and -1>0 becomes false. So it come out of loop.
