More than one class in the .php file

Hello guys.
I have more than one class in my Plugin. I have the class "statuscheck","SignUpdate" and "FallingBlocks"! All the classes are in one .php file.....But what of this classes I must write into the plugin.yml in the main: ?

Thanks Marcelo234

The Main class of the plugin, the one with onEnable function

The class which extends PluginBase.

I have

use McKaff_FallingBlocks\SignUpdate;
use McKaff_FallingBlocks\statuscheck;

and in the onEnabl part this:


$this->getServer()->getScheduler()->scheduleRepeatingTask(new SignUpdate($this), 40);$this->getServer()->getScheduler()->scheduleRepeatingTask(new statuscheck($this), 40);

and than my classes!


But the server crash!


Fatal error: Cannot declare class FallingBlocks\statuscheck because the name is already in use in C:\Users\Marcelo\Desktop\McKaff_FallingBlocks\plugins\McKaff_FallingBlocks\src\McKaff_FallingBlocks\FallingBlocks.php on line 273

it sayed it is too long...
