This is happening when I execute the command /punish MarcoHan bad

 

Your trying to get the 3rd argument with warn reason but yet checked if there's only 2

 

If i check it as three the command doesn't work at all, theres also only Two Arguments punish being the main Command and MarcoHan and bad being the arguments

 

Then add a argument?

 

Well your current code state doesn't work either. So are you going to fix the runtime error now and debug your logic error or live with both?

 

@Marcohan You need to know that java and us(humans) count differently:

• ......Java: 0 1 2 3 4 5 6 7 8 9
• ................|.|..|.|..|.|..|.|..|..|
• Humans: 1 2 3 4 5 6 7 8 9 10

So here, you are asking for args[1] and args[2] to a java program, so for us this would be args[2] and args[3] ! The is why your error throws arrayindexoutofboundsexception: 2. Because 2 in java is 3 for us! but the is no argument n°3 (for us humans) !

 

I would think he would know

 

@teej107 Oh my bad, but still, he uses "human numbers" in his if statement.
