error in the code

[Greenleaf]

Hi, I have to complete a code. There's an array containing objects called fish. The method

 public void disegna(Graphics2D g, Applet parent);

is used to draw each fish in the array. I wrote the following piece of code:

 for ( int i=0 ; i < pesciArray.length; i++)
      {  ((OggettoAnimato) pesciArray[i]).disegna(Graphics2D g2, Applet parent);
      }

and when I compile it, it tells me that ')' is missing. As no ')' is missing, the mistake is of another nature. pelase help me!

If the array is defined as

OggettoAnimato[] pesciArray = new OggettoAnimato[your number of fish];

then there's no need to cast it. You can just call the method like this:

pesciArray.disegna(Graphics2D g2, Applet parent); "When you have eliminated the impossible, whatever remains, however
improbable, must be the truth." ~ Arthur Conan Doyle

No, the array is defined as

 Object[] pesciArray

.
The method "disegna" is used for objects of OggettoAnimato so I must cast it.

I'm sorry, it's early in the morning....

Change

((OggettoAnimato) pesciArray).disegna(Graphics2D g2, Applet parent);

to simply

((OggettoAnimato) pesciArray).disegna(g2, parent); "When you have eliminated the impossible, whatever remains, however
improbable, must be the truth." ~ Arthur Conan Doyle
