Setting Final Boolean Value

Hello, this is probably a stupid question as my knowledge of java is small at the moment, but I'm working on it. Well anyways my problem is setting the value of a Boolean with the modifier Final. It appears I have to set the Booleans modifier to a final because I am running it in a Bukkit scheduler. So basically I try to set the value of a final Boolean and it says: "The final local variable isingame cannot be assigned, since it is defined in an enclosing type." Where isingame is my Boolean name. Here is a portion of my code:

Code:java

final boolean isingame = false;
if(ingame.isEmpty()){
isingame = false;
}
BukkitScheduler scheduler = Bukkit.getServer().getScheduler();
scheduler.scheduleSyncDelayedTask(this, new Runnable() {
@Override
public void run() {
isingame = true;
for(Player redplayers : red){
World world = (World) getConfig().get("redspawn" + ".world");
int x = (int) getConfig().get("redspawn" + ".x");
int y = (int) getConfig().get("redspawn" + ".y");
int z = (int) getConfig().get("redspawn" + ".z");
Location loc = new Location(world,x,y,z);
redplayers.teleport(loc);
redplayers.sendMessage(ChatColor.RED + "You are on the red team!");
                          }

So as you can see I have set the Boolean isingame to a final modifier because of this scheduler. So my question is, how can I set a final Boolean's value, or how can I run a normal Boolean without the final modifier in a Bukkit Scheduler?

I have a couple of ideas.

1. One involves making a new class and using the constructor to pass in values. Possibly more refactoring than you want to do (if you can avoid it).

2. Maybe you could make a method. And define one of the method parameters to be final. Then call the method and pass in your boolean flag, isingame.

For my code, I went with option one... So I know it works. But I've never actually tried option two, so I'm not sure if it'll work.

 

dont use nested classes and you wont hit such issue.

 

The variable needs to be final because it's local and you're using an inner class. I'd recommend moving the boolean to the class level. Also, why instantiate a Location for every single player if it's going to be the exact same?

Put in final Boolean array cap 1.

Set 0 index to boolean

Get boolean back from 0 index

 

But my laziness

Thanks that makes so much sense now that I think about it.

Well, how about using an object wrapper?

 

you can use blackmagic to change that field, it will be outlined to both classes - outer and nested.
