JavaFx BarChart( "Ghafla Kenya News/music Title Search Terms")

I was working on a project that involved the New York times article search api ,its the best API around the project was to have a look of who is mentioned in most of the Kenyan articles.Everything was just fine but most of the name are of politicians and athletes and i was very much interested in musicians.I had to look for more  local content,searching around  i came across ghafla!Kenya has 9380 Kenyan articles  under music category at the time of writing this post.
Getting all the 9380 titles was very easy with the help of kimono i was able to crawl 7855 titles/9380 titles.Still trying to crawl the rest 1525 pages.
7855 pages was really significant for my project.I downloaded the data in csv format from my kimono API page.

NB:the data is under news/music

Searching companies in Kenya i.e safaricom,airtel,tuskys,nakumatt

Companies result search

Searching politicians  i.e uhuru,ruto,raila,sonko

Searching socialite  i.e huddah,sidika,risper

Searching musicians  i.e octopizzo,p-unit,sauti sol,elani,stl,jaguar,wahu,nameless

Parsing the csv file to return only titles with quotes omitted the methods returns an observableList

public ObservableList<String>  getHeadlines(){
        try {

            path=Paths.get("list.csv");

            s=Files.readAllLines(path);

           } catch (IOException ex) {
           
        }
         for(String st:s){
         
            String rry[]=st.split(",");

            //do away with the quote marks
            String title=rry[1].substring(1, rry[1].length()-1).toLowerCase();
           
            list.add(title);
        }

        return list;
    }

Getting the keyword count method

public int getKeywordFrequency(){
   
    for(String line:list){
     
        if(line.contains(keyword)){
            count++;
        }
    }

    return count;
}
