java - How to use compareToIgnoreCase -

i given example on how alphabetically sort actor objects in array.

public class alphasortingexchange {  public static void main(string[ ] args)  {          string[ ] names = {"joe", "slim", "ed", "george"};          sortstringexchange (names);          ( int k = 0;  k < 4;  k++ )             system.out.println( names [ k ] );   }    public static void sortstringexchange( string  x [ ] )   {         int i, j;         string temp;          ( = 0;  < x.length - 1;  i++ )         {             ( j = + 1;  j < x.length;  j++ )             {                       if ( x [ ].comparetoignorecase( x [ j ] ) > 0 )                       {                                             // ascending sort                                   temp = x [ ];                                   x [ ] = x [ j ];    // swapping                                   x [ j ] = temp;                         }                }          }   } } 

i allowed follow sort of format in sorting array. netbeans not liking "comparetoignorecase" statement in code, giving error

"cannot find symbol: method comparetoignorecase(actors) location class actors"

. below sorting function.

public static void sortactors(actors actors[]) {      int i, j;     actors temp;      (i = 0; < actors.length - 1; i++)     {         (j = + 1; j < actors.length; j++)         {             if (actors[i].comparetoignorecase(actors[j]) > 0)             {                 temp = actors[i];                 actors[i] = actors[j];                 actors[j] = temp;             }         }     } } 

this object array , example of object in array. said before, can use comparetoignorecase. @ loss @ how use function

private static void createactorslist() {      actors[] actors = new actors[constants.number_of_actors];      actors ladyviolet = new actors();     ladyviolet.setname("lady violet");     ladyviolet.setdialogue("dialogue");     ladyviolet.sethappiness(0);     ladyviolet.sethealth(100);     actors[constants.violet] = ladyviolet; } 

any or solution appreciated!

thanks in advance!

your actor class doesn't have comparetoignorecase method. mean call method on 1 of class's fields, e.g.,

if (actors[i].getname().comparetoignorecase(actors[j].getname()) > 0) 

if method needs on actor class, you'd have write own implementation:

public int comparetoignorecase(actor actor) {     return this.name.comparetoignorecase(actor.name); }
