Calculating time(I don't know where is the error.)

Hi!

After a long break, i want to re-start coding plugins - And since the start the command prompt showed me an error, but don't know why... It's just a little test-plugin.

The Error:

PHP:

My "Cmd" Class, implementing the CommandExecutor-Interface:

PHP:

public class Cmd implements CommandExecutor {
 
protected TR mc;
public Cmd(TR mainclass){
mc = mainclass;
}
 
@Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if(cmd.getName().equalsIgnoreCase("Test_RA")){
if(sender instanceof Player){
repairInv((Player)sender);
}
}
return true;
}
 
 
void repairInv(Player p){
int max = mc.timeperms.keySet().size();
int c = 0;
for(String perm : mc.timeperms.keySet()){
if(p.hasPermission("Test_RA." + perm)){
int wait = getWaitingTime(p);
if(wait == 0){
reloadTimestamp(p, perm);
for(ItemStack is : p.getInventory().getContents()){
ItemStack isn = new ItemStack(is.getTypeId(), is.getAmount());
isn.addEnchantments(is.getEnchantments());
p.getInventory().remove(is);
p.getInventory().addItem(isn);
}
p.sendMessage("WORKS!");
break;
}else{
p.sendMessage("WAIT!");
break;
}
}
c++;
}
if( c != max ){
p.sendMessage("NOPERM!");
}
}
 
int getWaitingTime(Player p){
if(mc.pt.containsKey(p.getName())){
TimeStamp ts = mc.pt.get(p);
ts.setNew(System.nanoTime());
return ts.calculateDifference();
}else{
return 0;
}
}
 
void reloadTimestamp(Player p, String perm){
mc.pt.put(p.getName(), new TimeStamp(0, 0));
}
 
}

TimeStamp Class:

PHP:

public class TimeStamp {
 
private long before, after;
public TimeStamp(long old, long now){
before = old; after = now;
}
 
public void setOld(long o){
before = o;
}
public void setNew(long n){
after = n;
}
public long getOld(){
return before;
}
public long getNew(){
return after;
}
public void reset(){
before = 0;after = 0;
}
public int calculateDifference(){
return (int) ((after - before) * 1000000000);
}
 
}


What is wrong? I did not get it...
Can anyone maybe help me please ?

You didn't give enough informations.

 

Ribesg I already tryed to solve it by myself, but failed.

Oh, and here the line where the error "happens" (Sorry that i've forgotten to post it before ...):

Code:

ts.setNew(System.nanoTime());

The rest of the code ist above.

 

ts is null.

 

But it can't, I surrounded it by an if-query - Oh..

if(mc.pt.containsKey(p.getName())){
TimeStamp ts = mc.pt.get(p);

I see, sorry xD!

Thanks !
