Hello,

I was trying to execute the program on Pg 346 from Head First Java, MiniMusicCmdLine but the below error message displayed. I have gone through the progream multiple times but could not located what is causing this error.


C:\Library\Headache\Pro\Player>javac MiniMusicCmdLine.java
MiniMusicCmdLine.java:45: class, interface, or enum expected
}→
^
1 error

Apart from the fact that there some unknown methods in your cord (e.g. ParseInt), it seems that there is a strange character at the end of your file. Maybe you copy/pasted the code and it left some strange characters ? Remove the last line, and retype "}".

I have typed in everything. I just noticed that there was an extrac closing curly brace at the last which was not posted in this thread which I removed now but getting differnt error now.


C:\Library\Headache\Pro\Player>javac MiniMusicCmdLine.java
MiniMusicCmdLine.java:8: cannot find symbol
symbol : method ParseInt(java.lang.String)
location: class java.lang.Integer
int instrument = Integer.ParseInt(args[0]);

but getting differnt error now.

That's the error I was talking about. Check the name of your method (tip: Java is case-sensitive)

You shouldn't type anything. You should copy-and-paste, then you are sure you are posting real code.
