You can do something like the following method..

    int counterChars = 0;

    for (int i = 0; i < stringArray.length; i++) { 

        int counterLetters = 0; //declare counter for for amount of letters in each string in the array 

        for (int j = 0; j < stringArray[i].length(); j++) { 


            // below pretty self explanatory extracting individual strings and a
            charsInArray[counterChars] = stringArray[i].charAt(counterLetters);

            counterLetters++;
            counterChars++;
        }
    }
