skip multiple characters while adding to a hashmap in for loops

I have a string:

string[] = {'[','hey', ',' , 'how', ',', 'are', ',', 'you', ']' }

I'm writing this to a hashmap, I want the for loop to ignore all the commas. I tried something like this:

for(int i = 0; i<map.size(); i++){
           if(string[i].equals(",")){
               break;
           }
           System.out.println(map.get(string[i]));
       }

I know it breaks after the first comma.

output is like : [ hey

I want the output to be: hey how are you

How to solve this?
