Random string condition in java

I wrote a program that has a constructor called Word_generator(). Inside of this constructor, there is an instance variable of type int called count. When I run the program, and look at the results, I noticed that the program finished even though I see no way for count to have increased. The reason that this is bothering me is because count is used as part of the conditional check for a while loop at the end of the constructor.

For reference, here is the code I am working on:

private String[] array = {"hello", "hi", "what is your name"};

private String getRandomCharacter() {
    return array[random(array.length)];
}

private int random(int length) {
    return new Random().nextInt(length);
}

protected Word_generator() {
    boolean running = true;
    int count = 0;
    int max = 200;
    while (running) {
        StringBuilder sb = new StringBuilder();

        for (int i = 0; i < 1; i++) {
            sb.append(getRandomCharacter());
            System.out.println();
            System.out.println("Word-->");
        }

        System.out.println(sb.toString());


        if (count++ == max) {
            running = false;
            System.out.println("finished");
        }
    }
}
public static void main(String[] args) {
    new Word_generator();

}

The value of count is being increased at this line if (count++ == max){...} Here, first of all count is checked whether equal to max, if equals then running is set to false and loop is finished; else count is incremented by one.
