ArrayList of String[] array

[Nitish Gupta]

One of Java function's argument is List<String[]>

jArrayList = autoclass('java.util.ArrayList')   
jString = autoclass('java.lang.String')
words = ['a', 'b', 'c']
javaWords = [jString(w)  for w in words]
arraylist = jArrayList()
arraylist.add(javaWords)

But I get the following JavaException: No methods matching your arguments when I call arraylist.add(javaWords).

What is the solution for this?

Your `javaWords` variable is a Python-List. And of course, a Java ArrayList.add(.) won't be able to use it. 

I think the correct syntax is this: 

jArrayList = autoclass('java.util.ArrayList')   
jString = autoclass('java.lang.String')
words = ['a', 'b', 'c']
arraylist = jArrayList()
for w in words:  
    arraylist.add(jString(w))

Sorry, I think you misunderstood my question. I want to make a ArrayList<String[]> and not ArrayList<String>.

In pyjnius, String[] are expressed as python lists, but when I add one to ArrayList, it doesn't work.

jString = autoclass('java.lang.String')

jArrayList = autoclass('java.util.ArrayList')

jal = jArrayList()

jsl = jArrayList()

jsl.add(jString('a'))

jsll = jArrayList()

jsll.add(jString('b'))

jal.add(jsl)

jal.add(jsll)

BasicTextAnnotationBuilder = autoclass('edu.illinois.cs.cogcomp.annotation.BasicTextAnnotationBuilder')

BasicTextAnnotationBuilder.createTextAnnotationFromListofListofTokens(jal)

---------

This gives : 

JavaException: JVM exception occurred: [Ljava.lang.Object; cannot be cast to [Ljava.lang.String;
