Method changeFlowers is failing with Index Out of Bound Exception.
I am new to java, I am calling method "changeColor()" of already instanciated FishOne (Arraylist rederable class) But it is failing with Index Out of Bound Exception.
public void changeFlowers(int i)
{
FlowerOne f1 = (FlowerOne)(this._fishes.get(i)); // Is this the right way to call ????
f1.changeColor(this._theme);
}
Code below Aquarium.java, FishOne.java Thanks for your help in advance.
Aquarium.java,

try{
canvas = this._surfaceHolder.lockCanvas(null);
synchronized (this._surfaceHolder) {
this.onDraw(canvas);
}
}finally{
if(canvas != null){
this._surfaceHolder.unlockCanvasAndPost(canvas);
}
}
}
protected void onDraw(Canvas canvas) {
this.renderBackGround(canvas);

renderable.render(canvas);
}
