## Creating the environment

The first executable statement in our example obtains a Gurobi environment (using the GRBEnv() constructor):

   GRBEnv env = new GRBEnv("mip1.log");

Later calls to create an optimization model will always require an environment, so environment creation is typically the first step in a Gurobi application. The constructor argument specifies the name of the log file.
