ArrayList size difference

what's the difference?
ArrayList[MAXPLAYERS + 1] PlayerInfo;
vs
ArrayList PlayerInfo[MAXPLAYERS + 1];

both works well

Re: ArrayList size difference

I'm surprised that ArrayList[MAXPLAYERS + 1] is even allowed as only dynamically sized array are supposed to support brackets after the type according to the docs.

i.e.

PHP Code:


		
			
ArrayList[] PlayerInfo = new ArrayList[MaxClients + 1];

vs.

PHP Code:


		
			
ArrayList PlayerInfo[MAXPLAYERS + 1];

Note that the first would only work inside a method, although you could split it into two parts, like so:

PHP Code:


		
			
ArrayList[] PlayerInfo;

//in a method such as OnMapStart
if (PlayerInfo != null)
    delete PlayerInfo;

PlayerInfo = new ArrayList[MaxClients + 1];

Re: ArrayList size difference

I using this

PHP Code:


		
			
ArrayList[MAXPLAYERS + 1] PlayerInfo;



    for(int i = 1; i <= MaxClients; i++)

        PlayerInfo[i] = new ArrayList(5);

MAXPLAYERS is a constant value, so I do not see any purposes of creating an array with dynamic length.
Just create fixed-length array.

PHP Code:


		
			
ArrayList PlayerInfo[MAXPLAYERS + 1]; //Global variable

void OnPluginStart()  //Or somewhere else
{
    for(int i = 1; i <= MaxClients; i++)
    {
        PlayerInfo[i] = new ArrayList(5);
    }
}

What version of the compiler are you using? This does not compile for me in any of 1.7, 1.8, 1.9, or 1.10.
