importing-and-exporting

To declare any class as a package that you can import in another class, use package:

package frc.robot;
 
public final class Constants {
 
}

To import that class, use import:

import frc.robot.Constants

The Constants class

In this class, we declare multiple subclasses holding variables that store, you guessed it, constants. Examples of information that should be held in a constant include pin mappings, & wheel diameters.

The following details the subclasses that a Constants class should contain:

• DriveConstants
  • For DriveSubsystem
  • e.g. ports for motors and encoders
• ModuleConstants
  • For SwerveModule
• OIConstants
  • Stands for “Operator Interface”, aka the stuff that pertains to driver input
  • e.g. driver controller port ID
