why am I getting the below error while running the Chrome driver?

package AutomationSample;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
System.setProperty("webdriver.chrome.driver", "C:\\Users\\UserName\\Desktop\\chromedriver_win32");
WebDriver driver= new ChromeDriver();
driver.get("https://www.youtube.com/");
the above is my code and I have added all the selenium related jars into the project.
am getting the below error while running the Chrome driver:
Error: Unable to initialize main class AutomationSample.HelloWorld
Caused by: java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver
I am using Chrome - Version 91.0.4472.114 (Official Build) (64-bit)
and I am using chrome driver - 32 bit and my OS is windows 10 -64 bit.
Can you please help me to rectify this error?

cause you are missing class and method, one such method is main()
You need to have a method like below :
public static void main(String args[]) {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\UserName\\Desktop\\chromedriver_win32");
WebDriver driver= new ChromeDriver();
driver.get("https://www.youtube.com/");
}
and obviously a class in which you will have this method.

you have to pass the driver extension like below :
System.setProperty("webdriver.chrome.driver", "C:\Users\UserName\Desktop\chromedriver_win32.exe");
WebDriver driver= new ChromeDriver();

System.setProperty("webdriver.chrome.driver","C:\\Users\\UserName\\Desktop\\chromedriver_win32");
has to be:
System.setProperty("webdriver.chrome.driver","C:\\Users\\UserName\\Desktop\\chromedriver_win32.exe");
you forgot .exe

Appium driver NOT suggesting removeapp() function inside the code base

I want to user driver.removeapp({bundleID}); command in my appium script BUT IDE NOT suggesting this method even I've imported io.appium.java_client.*;

You need to double check the declaration of your driver variable:
public AppiumDriver driver;
driver = new IOSDriver(appiumURL, capabilities);
driver.removeApp(bundleId);

public static void main(String[] args){
WebDriver driver = new ChromeDriver();
System.setProperty("WebDriver.Chrome.driver", "E:\\chromedriver.exe");
driver.get("https://www.google.com");
}
}

The error says it all :

The following phrases from the error implies that there is an error in the line containing webdriver.chrome.driver
The error can be either of the following :
Error in the System Class Method setProperty()(including sequence) :
System.setProperty()
This line should be the very first line in your script.
Error in the specified Key :
"WebDriver.Chrome.driver"
Error in the Value field :
"E:\\chromedriver.exe"
You have to pass the absolute path of the WebDriver through either of the following options :
Escaping the back slash (\\) e.g. "C:\\path\\to\\chromedriver.exe"
Single forward slash (/) e.g. "C:/path/to/chromedriver.exe"
Your code seems to be having two issues as follows :
First issue is in specifying the Key which instead of "WebDriver.Chrome.driver" should have been "webdriver.chrome.driver" as follows :
System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");
Second issue is in the sequence of mentioning the Key "webDriver.chrome.driver" in your program which should be before WebDriver driver = new ChromeDriver(); as follows :
System.setProperty("WebDriver.Chrome.driver", "E:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://www.google.com");

I have seen many people are using wrong sequence.
the sequence should be.
First set the property and then launch the browser
System.setProperty("webdriver.chrome.driver", "F:/chrome/chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.navigate().to("https://www.google.com");

Download the chromedriver version corresponding to the chrome version in your system from https://chromedriver.chromium.org/downloads . Unzip the file and run the below code in the IDE.
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Selintroduction {
public static void main(String[] args) {
//Invoking browser
System.setProperty("webdriver.chrome.driver","C:\\Users\\HP\\Downloads\\chromedriver_win32\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
}
}
(Path would depend on your file location in the PC.)

I was facing the same error when my code was like so:
System.setProperty("webdriver.chrome.driver","C:\\Users\\abs\\chromedriver_win32.exe");
It works after adding "chromedriver" before ".exe" like so:
System.setProperty("webdriver.chrome.driver","C:\\Users\\abs\\chromedriver_win32\\chromedriver.exe");

You have to use System.setProperty not the System.getProperty as follows.
System.setProperty("webdriver.gecko.driver",
"C:\\Selenium WebDriver\\geckodriver\\geckodriver-v0.17.0-win64\\geckodriver.exe");

I have noticed that you are using wrong syntax, to opening the browser.
Instead of using System.getProperty, You have to use System.setProperty as mentioned below.
System.setProperty("webdriver.gecko.driver", "C:\\Selenium WebDriver\\geckodriver\\geckodriver-v0.17.0-win64\\geckodriver.exe");

How to get screenshot from RemoteWebDriver server instead of local FirefoxDriver?

I am running Selenium WebDriver test on a remote PC from my laptop(java client), by using RemoteWebDriver. But RemoteWebDriver haven't provided screenshot API to directly get a screenshot of remote PC. Googled a lot but found seems need use to Json API to get it from remoteWebDriver server directly. Anyone can give me some instruction about how to do that? Thanks.

The RemoteWebDriver must be augmented before you can use the screenshot capability. As you have no doubt already found, attempting to cast without augmenting results in an exception.
WebDriver driver = new RemoteWebDriver( ... );
driver = new Augmenter().augment( driver );
( (TakesScreenshot)driver ).getScreenshotAs( ... );

I was able to get this working...here is what you need to do:
1) Create a new class file in a Util directory or somewhere
package com.util;
import java.net.URL;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriverException;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.DriverCommand;
import org.openqa.selenium.remote.RemoteWebDriver;
public class ScreenShotRemoteWebDriver extends RemoteWebDriver implements TakesScreenshot {
public ScreenShotRemoteWebDriver(URL url, DesiredCapabilities dc) {
super(url, dc);
}
#Override
public <X> X getScreenshotAs(OutputType<X> target) throws WebDriverException {
if ((Boolean) getCapabilities().getCapability(CapabilityType.TAKES_SCREENSHOT)) {
return target.convertFromBase64Png(execute(DriverCommand.SCREENSHOT).getValue().toString());
}
return null;
}
}
2) Then...where ever you start the RemoteWeDriver, replace with this code:
driver = new ScreenShotRemoteWebDriver(new URL(-PUT YOUR HUB URL HERE-),cap);
Your screenshots will be stored locally.
Hope this helps.

I think this is the best way:
public<T> Object getScreenshotAs(OutputType<T> outputType) {
Augmenter augmenter = new Augmenter();
TakesScreenshot ts = (TakesScreenshot) augmenter.augment(driver);
return ts.getScreenshotAs(outputType);
}

Here's another solution:
https://groups.google.com/d/topic/selenium-users/NLHXlhPrADs/discussion

The RemoteWebDriver does not implement the TakesScreenShot and the methods described here to cast the instance of RemoteWebDriver to TakesScreenShot will cause a ClassCastException. I'll see if I can find a solution as I'm interested in doing the same.
The Augmenter will "enhance the interfaces implemented by this instance of WebDriver iff that instance is a RemoteWebDriver". Depending on how the RemoteWebDriver is configured and how the selenium server is running on the remote host, it may be possible to get a screen shot in using the org.openqa.selenium.remote.Augmenter.
I've configured the RemoteWebDriver to use DesiredCapabilities.htmlUnit() capabilities and this gives an ClassCastError. If the RemoteWebDriver is configured with the capabilities of a driver that implements the TakesScreenshot interface, then a ClassCastException may not occur, though I have yet to test this.
From the TakesScreenshot interface, the known implementing drivers are: AndroidDriver, AndroidWebDriver, ChromeDriver, EventFiringWebDriver, FirefoxDriver, InternetExplorerDriver, IPhoneDriver, IPhoneSimulatorDriver, and SafariDriver
