Re: simplest of code

OK................

I have the following code:-

*********************

OSV = ((mid_price_close - PDCC)/PDCC) / btheta;

//************************************************************************
   // run weka and make a prediction
     /**
    * Performs a prediction.
    *
    * @param v the value of the input variable to use for making a 
prediction
    * @return the predicted value (class index), returns -1 if it fails 
to make prediction
    * @throws Exception if prediction fails
    */
   try {
       // [B] create instance
       // create the current instance
       double[] values = new double[header.numAttributes()];
       for (int i = 0; i < values.length; i++)
         values[i] = Utils.missingValue();
       // - numeric
       values[0] = OSV;
       DenseInstance currentInstance = new DenseInstance(1.0, values);
       currentInstance.setDataset(header);

       // [C] classify nominal class
       // classifyInstance() just returns the index of the predicted 
label (the one with the highest probability) as a double
       double prediction = cls.classifyInstance(currentInstance);
       System.out.println("prediction: " + prediction);

       return (int) prediction;
   }

*******************************

Errow message:-

Syntax error, [on the last line] insert "Finally" to complete try 
statement ??
