Get ArrayList Size

i need to get the arraylist size by .Size() and how much players are in the arraylist its will create a line in scoreboard with their name, ive made a scoreboard but i need that the how much players its will be the same lines as size in the ArrayList scoreboard.addLine("and their name")

 

Use

Code:java

if(arraylist.size() == 4){ # can be any number
//do stuff
}

Or use a for loop somewhere

 

nope i didnt meant like that if its automaticaly gets the number from the arraylist its will check amount there inside the array and its will create lines of scoreboard.addLine() of the amount of the players

 

Something like this might work:

Code:java

for(String playerName : i)
{                 
     yourscoreboard.addLine(playerName);
}

 

Sur whats does the "i" means the arraylist ?
