Solved why using getPLayer() != null instead of isOnline()?

all is in the title ,

good night

 

Once checks if the returned value is null, the other invokes a method that returns true if the player is online. Not sure why you are comparing them. They do completely different things. You may in fact end up needing to call them both in the same block of code.

 

isOnline is for using the OfflinePlayer class, which Player inherits. Players can be null, but OfflinePlayers cannot.

 

Any variable or method return not pointing to a primitive can be null.

 

getOfflinePlayer(...) will create and return a new OfflinePlayer if the specified one doesn't exist. getPlayer(...) will return null if the player is not online. The reference can be null, but the method isn't going to return null.

 

ok so if i undestant well,

___> will return true or false

______> will rerurn an online player name or NULL

______> return True , or NULL since he look in the player online

i was using the last code but i was getting NULL when the player wasent online, thats why i ask the diferance in those code,

Thanks, Sagacious_Zed Tirelessly

 

bellegueule Your last option won't return null, it'll throw a NullPointerException. There's a very large difference.
