variable prob

[oll3i]

whu eclipse highlights the return balans as an error not declared variable
although it's declared
double balans = Double.valueOf( dane[dane.length].trim()).double Value();

private double get_sr_dost(String numer_konta)
			{     
	
	
	try{
	    
	    
	    BufferedReader in = new BufferedReader(new FileReader("konta//"+numer_konta+".txt"));
		       
	    
	    
	    String wczytane_dane="";
	    String line = in.readLine();
	
	  
	  while((line = in.readLine()) != null)   {   
		  wczytane_dane+=line;
	    	line = in.readLine();
	    	wczytane_dane+=":";
	  }
	  
	 
	  
String[] dane=wczytane_dane.split(":");	    
double  balans = Double.valueOf(dane[dane.length].trim()).doubleValue();
in.close();
	  }catch (FileNotFoundException e) {
		    System.err.println("Nie ma takiego konta(File not found!)");
	  }catch (IOException e) {
	          System.err.println(e);
	  } catch (NumberFormatException e) {
	         System.out.println("NumberFormatException: " + e.getMessage());    
	  }catch (Exception ex)  {
      ex.printStackTrace();  }
	 
	
	return balans;
}

Would you mind posting yoru solution in case someone else has the same trouble?

(I'm guessing it was to do with dane[dane.length] , but I'd like to know for sure!)

You declared it inside the try block and tried to return it outside the try block where it was now out of scope.
