I'm fairly new to java programming. this is my first java code. it's simple and straight to the point. I hope to create a program that solves algebra and other simple maths

 class myformlr
{
   double base, height, triArea;
   void calc()
  {
   triArea = (base*height)/2;
   System.out.println("Area of the triangle =" + triArea);
  }
  void values(double b, double h)
  {
   base = b;
   height = h;
  }
}
class trigarea
{
  public static void main(String args[])
  {
   myformlr trig = new myformlr();
   trig.values(5,4);
   trig.calc();
  }
}

post yours if you have any
