Unable to Launch any Browser Drivers using Selenium, testng

Question

I am building a testing framework for a project using Java selenium and Testng I am using below maven dependencies -

<properties>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
        </dependency>

        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
            <version>3.141.59</version>
        </dependency>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>21.0</version>
        </dependency>
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>6.14.3</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

And i am trying to launch the drivers as below -

 case CHROME: System.out.println("*****Launching Chrome Driver****");
                             System.setProperty("webdriver.chrome.driver","/home/path/Desktop/chromedriver.exe");
                     
                             driver = new ChromeDriver();
                             driver.get("https://www.google.com/");

                case FIREFOX: System.out.println("***LAUNCHING FIREFOX BROWSER****");
                              System.setProperty("webdriver.gecko.driver","/home/path/Desktop/geckodriver");
                              driver = new FirefoxDriver();
                              driver.get("https://www.google.com/");

I tried by giving both .exe and without .exe

Yet the drivers are ot getting launched and i am getting below error -
