Every protractor example I can find on the internet seems to use browser.get with a web URI.
browser.get
browser.get(\'http://localhost:8000\');
I think there is typo mistake. In "get" method you should include the URL in double quotes "".
Try using double quotes like below:
WebDriver driver=new FirefoxDriver(); driver.get('file:///E:/Programming%20Samples/HTML%20Samples/First%20Program.html');
