getCategoriesCount

Unable to get the code working.

public Map <String, Integer> getCategoryCounts(){
  Map <String, Integer> getCategories= new HashMap<String, Integer>(); 

    for (BlogPost post: getPosts()){
          int count =0;
      for (String category: post.getCategory()){
          count++;
          getCategories.put(category, count);
      }
    }
    return getCategories;
  }

getCategory returns a String, no need for the nested for loop.

Hope that helps!
