Problemer med String Array:(

[Richard87]

Jeg prover og endre storrelsen pa et array etter at jeg har deklarert det, men ingen ting fungerer slik jeg forventer:( (btw, kommer fra Visual Basic, ikke helt det samme... )

 

her er koden min:

public void populateList(int funksjon) {
 //String Popul[] = {"populating..."};
 //lstMain.setListData(Popul);
 String[] data  =   {"testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing","Testing"};
 switch (funksjon) {
 	case 0: //test purpose
   break;
 	case 1: //Fisk
   data = new String[0];
   data[0]= "Fisk";
   break;
 	case 2: //Kjott
   data = new String[0];
   data[0] = "Kjott";
   break;
 	case 3: //Fugl
   data = new String[0];
   data[0] = "Fugl";
   break;
 	case 4: //Vegetar
   data = new String[0];
   data[0]= "Vegetar";
   break;
 	case 5: //Hurtig
   data = new String[0];
   data[0]= "Hurtig";
   break;
 	
 	default: break;
 }
 
 lstMain.setListData(data);
 
 	
}

 

og her er alle de uforstelige feilmeldingene:(

HJELP!

du prøver å opprette string-tabell av lengde 0. Det er ikke så enkelt

java.lang.ArrayIndexOutOfBoundsException: 0

endre switch-casenen til "data = new String[1]" (eller et annet tall >0 )
