Question

I don’t understand this code can you explain me

grid is an int[][]
distbest is initialized

double distbest
int turn = 60;
if (g > 1)
   this.grid = turn(distbest * turn).grid;
else
   this.grid = turn(-distbest * turn).grid;

Answer 1

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.
