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?

How can I write something this: if(!string[i].equals(",") && !string[i].equals("[") && !string[i].equals("]"))

Instead of break, you should use continue.

continue will skip the rest of the lines, and move to the next iteration of the loop. Hence, the rest of the data will be written in the hashmap.

Edit:

I guess that you want to skip the characters that are not letters. In that case, you can do:

if(!Character.isLetter(string[i].charAt(0))){
    continue;
}

This will skip all those characters which are not letters.

I'm personally not a big fan of continue and break. I think 

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

is more linear.

Use continue instead of break operator.
