I have been trying to create a gui that calculates trigonometric functions based off of the user's input. I have had success in the GUI part, but my class that I wrote to hold information using inheritance seems to be messed up, because when I run it gives an error saying:
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - constructor ArcTrigCalcCon in class TrigCalc.ArcTrigCalcCon cannot be applied to given types;
required: double,double,double,double,double,double
found: java.lang.Double,java.lang.Double,java.lang.Double
reason: actual and formal argument lists differ in length
at TrigCalc.TrigCalcGUI.(TrigCalcGUI.java:31)
at TrigCalc.TrigCalcGUI.main(TrigCalcGUI.java:87)
Java Result: 1
and says it is the object causing the problem. Below Will be my code. First I will put up my inheritance class with cosecant secant and cotangent and then my original class with the original 3 trig functions:
{
public ArcTrigCalcCon(double s, double cs, double t, double csc, double sc, double ct)
{
// Inherit from the Trig Calc class
super(s, cs, t);
cosecant = 1/s;
secant = 1/cs;
cotangent = 1/t;
}
public void setCsc(double csc)
{
cosecant = csc;
}
public void setSec(double sc)
{
secant = sc;
}
public void setCot(double ct)
{
cotangent = ct;
}
}
Here is the first Trigonometric class:
public class TrigCalcCon
{
public double sine;
public double cosine;
public double tangent;
public TrigCalcCon(double s, double cs, double t)
{
sine = s;
cosine = cs;
tangent = t;
}
public void setSin(double s)
{
sine = s;
}
public void setCos(double cs)
{
cosine = cs;
}
public void setTan(double t)
{
tangent = t;
}
public void set(double s, double cs, double t)
{
sine = s;
cosine = cs;
tangent = t;
}
public double getSin()
{
return Math.sin(sine);
}
public double getCos()
{
return Math.cos(cosine);
}
public double getTan()
{
return Math.tan(tangent);
}
}
and here is the demo class to run the gui:
public class TrigCalcGUI extends JFrame implements ActionListener
{
// Instance Variables
