org.openqa.selenium.WebDriverException in Java

I am new to Automation and trying to learn Automation as a manual tester. I am trying to execute a simple java code to open a Chrome browser using Selenium Webdrivers and get the below exception. Tried all possible ways to resolve the same and still nothing works. Any help would really help. Thanks.
