How to handle alert and confirm boxes and avoid the Race Condition

Method 1
-----------
Alert alert = null;
Wait<WebDriver> wait = new WebDriverWait(driver, 10, 50);
try {
   alert = wait.until(ExpectedConditions.alertIsPresent());
} catch (TimeoutException ignored) {
}
if (alert != null) {
   alert.accept(); // this line throws the exception
}

Method 2
-------------

public void clickOkOnAlertDialog(String dialogText) {

        Sync sync = Sync.start(20);
        while (sync.continueWaiting()) {
            wait = new WebDriverWait(driver, pageTimeoutInSeconds);
            wait.until(ExpectedConditions.alertIsPresent());
            Alert statusConfirm = driver.switchTo().alert();
            junit.framework.Assert.assertEquals(dialogText, statusConfirm.getText());
            try {
                statusConfirm.accept();
                return;
            } catch (WebDriverException e) {
                sync.sleep(250);
            }
        }
        throw new TimeoutException("Unable to locate and dismiss alert dialog: " + dialogText);
    }
   
Method 3 (Not a good way though)
-----------

((JavascriptExecutor) driver).executeScript("window.alert = function(msg){};");
((JavascriptExecutor) driver).executeScript("window.confirm = function(msg){return true;};");
