Ruby string -> toCharArray

Ruby JRuby
#1

Hello,
I get fallowing error:

$ jruby jr.rb
jr.rb:33: for method tokenizer expected [[C, int, int]; got:
[java.lang.String,j
ava.lang.Integer,java.lang.Integer]; error: argument type mismatch
(TypeError)

It is caused by this code (commented fragemts in Java):

#String line = bufReader.readLine();
#…

char[] cs = line.toCharArray();

cs = String.new(“The import statement can be used to import a Java
Class.”)

char[] cs = line.toCharArray();

Tokenizer tokenizer = TOKENIZER_FACTORY.tokenizer(cs,0,cs.length);

tokenizer = tokenizer_factory.tokenizer(cs, 0, cs.length) # this line 33
tokens = tokenizer.tokenize()

How to modify that code to pass?

Cheers,
Tomasz Bak

PS There is the full code:
