public class XYData
{
  private
      String
          x = null;
      Float
          y = null;
      
      public XYData(String x, Float y)
      {
          this.x = x;
          this.y = y;
      }
      
      public String getX()
      {
          return x;
      }
    
      public Float getY()
      {
          return y;
      }
