Invert if, have tried multiple ways. cannot find error in code

when I run this code I get the error,

   at javaapplication1.JavaApplication1.bigger(JavaApplication1.java:32) 

(the inver if warning), however I have tried everything I can think of. I'm not sure what I'm missing here in order to have it compile.

 public static boolean bigger(int x, int y)
   {
    int biggerNum =0;
    int numBigger = 0;
    int [] data = new int[MAXVALUES];
    for(int curIndex = 0; curIndex < data.length-1; curIndex++)
    {
       if (bigger(data[curIndex],data[data.length-1]))
       {
           numBigger++;
       }
       else 
       {
        return false;
       }   

     }

   }
