//comment the above line and uncomment below line to use Chrome
//import org.openqa.selenium.chrome.ChromeDriver;

public class Selenium_1 {
        public static void main(String[] args) {
            // declaration and instantiation of objects/variables
            System.setProperty("webdriver.firefox.marionette","C:\\Program Files\\Java\\jre1.8.0_231\\lib\\ext\\geckodriver.exe");
            //System.setProperty("webdriver.chrome.driver", "/path/to/chrome driver");
            WebDriver driver = new FirefoxDriver();
            //comment the above 2 lines and uncomment below 2 lines to use Chrome
            //System.setProperty("webdriver.chrome.driver","G:\\chromedriver.exe");
            //WebDriver driver = new ChromeDriver();

            String baseUrl = "http://demo.guru99.com/test/newtours/";
            String expectedTitle = "Welcome: Mercury Tours";
            String actualTitle = "";

            // launch Fire fox and direct it to the Base URL
            driver.get(baseUrl);

            // get the actual value of the title
            actualTitle = driver.getTitle(); 

            /*
             * compare the actual title of the page with the expected one and print
             * the result as "Passed" or "Failed"
             */
            if (actualTitle.contentEquals(expectedTitle)){
                System.out.println("Test Passed!");
            } else {
                System.out.println("Test Failed");
            }



            //close Fire fox
            driver.close();
        }

This error message...

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableMap
    at org.openqa.selenium.firefox.FirefoxDriver

...implies that the file com/google/common/collect/ImmutableMap might be corrupted or there is some incompatibility between the version of the binaries you are using specifically with the guava version / dependency (maven).

You need to take care of a couple of things as follows:

In the System.setProperty() line you need to change webdriver.firefox.marionette to webdriver.gecko.driver. So effectively, the line of code will be:
```
System.setProperty("webdriver.gecko.driver","C:\\Program Files\\Java\\jre1.8.0_231\\lib\\ext\\geckodriver.exe");
```
Incase you are using maven deleting the corrup/incompatible .m2 folder can solve your issue.
Upgrade JDK to recent levels JDK 8u222.
Upgrade Selenium to current levels Version 3.141.59.
Upgrade GeckoDriver to GeckoDriver v0.26.0 level.
GeckoDriver is present in the desired location.
GeckoDriver is having executable permission for non-root users.
Upgrade Firefox version to Firefox v70.0 levels.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
(WindowsOS only) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
(LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint before and after the execution of your Test Suite.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your Test as a non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
