I am not sure, when you said you are not able to change compilation version. You can change as per below screen grab.

> ..project>right click>build path>configure build path >java compiler>

Do not forget to click on Apply after changing compilation version.

When you are working with Selenium you need to follow a few steps

//first you add your chrome driver path    
System.setProperty("webdriver.chrome.driver", "C:/Users/UMASHANKAR/Downloads/chromedriver_win32/chromedriver.exe");

// second you need to initialize the WebDriver object - and you did it
WebDriver driver=new ChromeDriver();

// third you need to tell to the WebDriver object where to go, what page to load 
driver.get("https://sdzclient-kpiregister.azurewebsites.net/"); 

//below is the login part
driver.findElement(By.id("userName")).sendKeys("SET_YOUR_USERNAME_HERE");
driver.findElement(By.id("passwords")).sendKeys("Gravity@123");
driver.findElement(By.id("btn-sdz-login")).click();

your error was throw because the driver didn't know where to go but you tried to send some keys instead of a driving page path
