I'm new to selenium web driver automation. When I try this code snippet to run, I got this error message. I'm getting nervous bcz I did it according to the online web tutorial. Please help me to go ahead.

Here is the code I tried.

package seleniumTest;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class TestWikipedia {

public static void main(String[] args) throws InterruptedException {

    WebDriver driver = new FirefoxDriver();

    driver.get("http://wikipedia.org");

    WebElement link;

    link = driver.findElement(By.linkText("English"));
    link.click();

    Thread.sleep(5000);

    WebElement searchBox;
    searchBox = driver.findElement(By.id("SearchInput"));
    searchBox.sendKeys("Software");
    Thread.sleep(5000);

    driver.quit();
}

}

Here is the error I have got in Eclipse console.

    There is nothing wrong with your code. It is a Java version problem. Which version of Java do you compile/run the code with? – Würgspaß Oct 26 '16 at 10:39

this kind of error

Unsupported major.minor version

indicate a problem on the java version. A general solution is to update the jdk1.8.

in this particular case i think that your project is developed with jdk1.8 and you are trying to compile with jdk1.7.

for completeness here you find the numbers associated with the java versions.

Java 9 = 53,
Java 8 = 52,
Java 7 = 51,
Java 6 = 50,
Java 5 = 49,
Java 4 = 48,
Java 3 = 47,
Java 2 = 46,
Java 1 = 45
