Using a classical approach, a simple multi-body gravitational framework for simulating the motion of stars within galaxies was created. Based upon this framework, four different models of the distribution of matter in galaxies were applied: a point mass core; a spherical core of uniform density; a spherical core plus a spherical halo outside of that core, both with uniform radius; a core of uniform density and a halo of density that dropped inversely in proportion to the square of the radius. This halo was representative of the dark matter, while the core represented visually detectable matter. Simulation results were compared with data on galactic rotations. Data was also taken on the collisions between disk galaxies and compared to existing galactic shapes. Conclusions based on these comparisons will be presented. The simulations were created using the Java programming language.
