method to public
. Which prevents the code checker from accessing it.
If you add the public
access modifier to the method like this:
public Map<String,Integer> getCategoryCounts(){ // <- Added public access modifier
Map<String,Integer> catCounts = new HashMap<String, Integer>();
for(BlogPost b : mPosts){
Integer count = catCounts.get(b.getCategory());
if(count == null){
count = 0;
}
count++;
catCounts.put(b.getCategory(),count);
}
return catCounts;
}
Then your code will work.
