public class Resources
-extends java.lang.Object
```
-
Encapsulates all of the resources based on which the program operates. - Each instance of JCGP contains a single instance of Resources. -

- The experiment's Resources object is passed to modules as the program operates, and - the actual parameter values can be obtained using getter methods. Note that, for code brevity, - this class's getters do not start with the word "get". For instance, to get the number of rows, - one would use rows() instead of getRows() which doesn't exist. - The fitness orientation of the problem being solved can also be retrieved using fitnessOrientation(). - Evolutionary strategies will typically use this to perform selection. -

- In addition to parameters, this class also offers utility methods. Any necessary random numbers - should be obtained using getRandomInt() and getRandomDouble() as these methods - use a particular Random object guaranteed to generate random numbers based on the seed - parameter. Functions from the selected function set can be obtained through this class as well. - Finally, printing to the console should be done via the resources using the report and print - methods, so that these prints also get sent to the GUI console (if one is present).

    println
    -
```
public void println(java.lang.String message)
```
    -
    Prints a message to the consoles ignoring - report interval. In other words, messages printed - using this method will always appear (though the - GUI console will still need to be flushed). -
    - This method automatically appends a line break to the message - being printed.
    -
    -
    Parameters:
    -
    message - the message to print.

```
public void print(java.lang.String message)
```
    -
    Prints a message to the consoles ignoring - report interval. In other words, messages printed - using this method will always appear (though the - GUI console will still need to be flushed). -
    - This method does not append a line break to the message - being printed.
