java.lang.IllegalStateException using ChromeDriver with Selenium Java

Code trials:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class SeIntro {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver","C:\\Users\\ramak\\Downloads\\chromedriver_win32.zip.exe" );
WebDriver driver=new ChromeDriver();
}
}
Snapshot:

chromedriver_win32.zip is a zip type file a format for compressed file archives, allowing packaging of multiple files and directories into a single file.
Where as System.setProperty() line expects the absolute path of the ChromeDriver binary executable.
Solution
You need to unzip the chromedriver_win32.zip and pass the absolute path of the ChromeDriver binary executable as follows:
System.setProperty("webdriver.chrome.driver","C:\\Users\\ramak\\Downloads\\chromedriver_win32\\chromedriver.exe" );

The method window() is undefined for the type Object

I am getting an error saying "The method window() is undefined for the type Object" and not sure why. This is what my code looks like:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Maximize2 {
public static void main(String[] args) {
// TODO Auto-generated method stub
WebDriver driver = new FirefoxDriver();
driver.get("https://login.yahoo.com/");
driver.manage().window().maximize();
}
}

The snippet above works for me with Selenium 2.53.1, Firefox 51.0.1 and Fedora 25.
Try to update your Selenium and browser and run the test again.

Try to do the setup for Eclipse like this:
Download and unzip Selenium Client Driver for Java
http://seleniumhq.org/download/#client-drivers
Create a new project
Right click on project in Package Explorer
Click “Properties”, then “Java Build Path”
Click “Add External JARs” and select all jar files from “libs” folder and "selenium-java-$VERSION.jar"
Run the snippet again
You should also consider using Gradle for your dependency management. This tutorial and googling for "gradle selenium" should help: https://gradle.org/uncategorized/video-tutorial-test-automation-selenium-web-application/

The path to the driver executable must be set by the webdriver.gecko.driver issue in selenium webdriver

I'm trying to run the following sample snippet
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Test
{
public static void main(String[] args)
{
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
//System.out.println("My new program");
}
}
When I run this code, getting the following error.
The path to the driver executable must be set by the webdriver.gecko.driver system property;
Firefox version is 48.0
Could anyone please help me to fix this issue.

If you are using windows follow the steps:
Right click my computer and select properties.
Click advanced settings->Environment variables.
Under System variable there should be variable named Path.
By the end of the path variable value add semi colon and then add specify your jecko driver's path. Example(C:\Jeckodriver).
Now compile the code. If it still throws exception then downgrade Firefox to 47.0.1.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Test
{
public static WebDriver driver;
public static void main(String[] args)
{
System.setProperty("webdriver.gecko.driver","Browser path.exe");
driver = new FirefoxDriver();
driver.get("http://www.google.com");
//System.out.println("My new program");
}
}

Download Gecko driver and extract to any folder. Specify gecko driver's path in path variable.

NoClassDefFoundError error while using Selenium with java

I am new to Selenium and I am trying to access google.co.in. My code is
public static void main(String[] args) {
String baseUrl = "https://www.google.co.in/";
WebDriver driver = new FirefoxDriver();

and I have also written two import statements after loading the appropriate jar file
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
I am new to both selenium and java..So please help..

You must add this library:
selenium-server-standalone-version.jar
and
selenium-java-version.jar
