driver.wait() throws IllegalMonitorStateException

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); is the best solution. Else, you have surround the driver.wait by synchronize block

You can only wait on an object if you've acquired the lock for it using synchronized.

I don't know whether you're meant to use wait using WebDriver - if you are, you'd need something like:

synchronized (driver)
{
    driver.wait();
}

However, if you're waiting for something to occur, it's more likely that there's an alternative method you're meant to be using. Perhaps WebDriverWait?

I hope this helps you

driver.manage().timeouts().implicitlyWait(long time, java.util.concurrent.TimeUnit unit); 

OR

WebDriverWait wait = new WebDriverWait(driver, long timeOutInSeconds);

WebElement element = wait.until(presenceOfElementLocated(org.openqa.selenium.By locator));

Please note that I have not executed this code as I don't have webdriver but I wrote this after referring to javadocs.

Please refer javadocs for more details on this.
