NullPointerExceptions with getTitles() and starter ques!

[albert...@gmail.com]

Hi, I'm using Processing to analyse ABC files.

I was just curious as to how the tutorials work - specifically this one - 

https://code.google.com/p/abc4j/wiki/Tutorial

Is the line - System.out.print("Title n°10 is " + aTune.getTitles[0]); - incorrect in how it calls getTitles()?

I am getting a NullPointerException at this point, 

my ABC file looks like this 

X: 1

T: Miller's Maggot, The

Z: Will Harmon

S: https://thesession.org/tunes/333#setting333

R: jig

M: 6/8

L: 1/8

K: Gmaj

Also, in the next part of the tutorial - 

Tune.Score score = aTune.getScore();
Iterator iter = score.iterator();
while (iter.hasNext())
System.out.println(iter.next());

What extra libraries do I need to load for Tune.Score to be recognised?

Thanks for any help.

ABC4j is great by the way!

Hi !

As usual, are you using SVN version or old downloadable JAR?

If you are using the SVN version, the tutorials in wiki are a bit outdated :-/ I have to understand how to upadte them...

Look an older topic on this group I explained the structure's changes I made.

Regards,

Sylvain

Hi, thanks for the response. I'm using the jar file. Is there a more recent file I should be using?

Hi, SVN is far more recent, but wiki documentation is not up to date yet.

Go to Source and Checkout : https://code.google.com/p/abc4j/source/checkout

you need a SVN client (e.g. Tortoise) or plug-in (in Eclipse, intelliJ...)
