Constructor Detail

Diffusion.Electron

public Diffusion.Electron(double x,
                          double y,
                          double xv,
                          double yv)

Creates a new electron

Parameters:

x - The initial x-coordinate

y - The initial y-coordinate

xv - The initial x component of the velocity

yv - The initial y component of the velocity

Diffusion.Electron

public Diffusion.Electron(double x,
                          double y,
                          double energy)

Creates a new electron, with the specified energy, but a random direction.

Parameters:

x - The initial x-coordinate

y - The initial y-coordinate

energy - The energy of the electron

Method Detail

paint

public void paint(java.awt.Graphics g,
                  double xscl,
                  double yscl)

Plots this electron (as a filled circle).

Parameters:

g - The Graphics surface on which to paint

xscl - The scaling factor for x coordinates

yscl - The scaling factor for y coordinates

update

public void update(double dt)

Updates the position and velocity of this electron to reflect a change in time. If the particle hits a wall, the appropriate momentum component will be negated.
