我添加了這個來創(chuàng)建一個隨機組名，現(xiàn)在我想驗證這個組名是否存在：public String generateRandomName(int length) {    char[] chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"            .toCharArray();    StringBuilder sb = new StringBuilder();    Random random = new Random();    for (int i = 0; i < length; i++) {        char c = chars[random.nextInt(chars.length)];        sb.append(c);    }    String randomString = sb.toString();    return randomString;}這是我的while循環(huán)：public boolean validateGroupNameIsCorrect(String groupName) {    int i = 1;    WebElement NewGroupText = driver.findElement(By.xpath("//*[@id='content']/form/span["+ i + "]"));    while (true) {        if (getNewGroupText().getText().equals(groupName));        return true;        System.out.println(i);    }}
