This section:

turn(distbest * turn)

means that there's a function turn that returns an object that contains grid that takes a double as a parameter. What's not shown in the code is the return type.

Hence, what I can say, is that the function is declared something like

Grid turn(double d);

where Grid (ficticious) has a public attribute of int[][] grid (that's why turn(distbest * turn).grid is possible).

I'm basing all this from the sample code listed above. The other turn is a parameter.

In addition to the turn variable which is an int type, there must also be a int[][] turn(double) method which is not shown. It's generally considered bad practice to name methods the same as variables because it causes exactly the type of confusion you're experiencing. If possible, considerer renaming either the variable or the method.

The code is pretty straightforward, so what about it do you not understand?

Perhaps what's confusing you is the double use of turn as both a variable name and a method name - turn(distbest * turn) is a method call, and the grid field of the returned object is the assigned to this.grid.
