Java Program to Return -1 if Point is on Left and 1 if Point is on Right

public class Main
{
    public static int check(float sx,float sy,float ex,float ey,float px,float py)
    {
        
        double sp = Math.sqrt(Math.pow(px-sx,2)+Math.pow(py-sy,2));
        double ep = Math.sqrt(Math.pow(px-ex,2)+Math.pow(py-ey,2));
        double se = Math.sqrt(Math.pow(ex-sx,2)+Math.pow(ey-sy,2));
        if (sp+ep == se)
            return 0;
        else if (sp+ep != se && sp < ep)
            return -1;
        else
            return 1;
    }
   public static void main(String[] args)
   {
      float sx = 0;
      float sy = 0;
      float ex = 0;
      float ey = 5;
      float px = 0;
      float py = -9;
      int result = check(sx,sy,ex,ey,px,py);
      System.out.println(result);
   }
}

Output:

-1
