Implement PageObjects using TestNg in selenium
Is LoginPageObjects also a LoginPageLocators?

LoginPageObjects extends LoginPageLocators


seems unlikely. Hence I would not make page object class extend locator class. I usually keep locator on the same page object class for sake of better cohesion. You may come across locators which are applicable for multiple page object classed but in any case page object class is not a page locator class.

public void verifyTitle(){


By and large convention has been to not keep verification/assertion in the page class. Only exception is the page object constructor which can be used to check is control is on write page.

Adding on to what Alexei already mentioned. Adding complete code example would help others to help you. Not everyone works with selenium/TestNG and would find it difficult to get context without complete code example.
