I had juz started to learn JAVA for 3 weeks time... so i would like to search for help.... about Runge-Kutta 4th Order Method, i got no idea on this. Well the basic idea of this assignment is to attach a 3 scroll bar which allow us to adjust the Resistor(R),Capacitor(C) and Voltage(E) value accordingly and a charging / discharging graph would be plotted automatically. I just dunno how to start with the code and equation.
BTW, can use Euler??
