### 11.6 EJS-Simulations packaged as Launchers

A number of physics courses, that demonstrate the application of the EJS program
for the simulation of elementary and advanced physical problems, are also combined
as Launcher packages. Individual solutions contained in them can be called via
double click. The packages, that are shortly described in the following are by
Wolfgang Christian, Francisco Esquembre and their colleagues. They can be called
directly via the link on the margin.

The advantage of these EJS Launcher packages in comparison to the OSP
packages discussed above, is , that changing the simulations does not require
advanced JAVA knowledge.

An active individual simulation can be transferred into the EJS console via the
context menu (callable via clicking on the simulation with the right mouse button).
In its windows code and visualization elements can be seen and edited. Thus
an existing solution can be quite easily used as starting point for further
developments.
