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

sendKeys method throwing an error in selenium like"The method sendKeys(char sequence[] )in the type webelement is not applicable for the string"

this is my class*****
```
package automation;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Test1 {
public static void main(String[] args)
{
System.setProperty("webdriver.chrome.driver", "C:/Users/UMASHANKAR/Downloads/chromedriver_win32/chromedriver.exe");
WebDriver driver=new ChromeDriver();
driver.findElement(By.id("userName")).sendKeys("https://sdzclient-kpiregister.azurewebsites.net/");
driver.findElement(By.id("passwords")).sendKeys("Gravity#123");
driver.findElement(By.id("btn-sdz-login")).click();
}
}
```
on Hover the SendKeys method will get an error like"The method sendKeys(char sequence[] )in the type webelement is not applicable for the string".***

When you are working with Selenium you need to follow a few steps
//first you add your chrome driver path
System.setProperty("webdriver.chrome.driver", "C:/Users/UMASHANKAR/Downloads/chromedriver_win32/chromedriver.exe");
// second you need to initialize the WebDriver object - and you did it
WebDriver driver=new ChromeDriver();
// third you need to tell to the WebDriver object where to go, what page to load
driver.get("https://sdzclient-kpiregister.azurewebsites.net/");
//below is the login part
driver.findElement(By.id("userName")).sendKeys("SET_YOUR_USERNAME_HERE");
driver.findElement(By.id("passwords")).sendKeys("Gravity#123");
driver.findElement(By.id("btn-sdz-login")).click();
your error was throw because the driver didn't know where to go but you tried to send some keys instead of a driving page path

I am not sure, when you said you are not able to change compilation version. You can change as per below screen grab.
..project>right click>build path>configure build path >java compiler>
Do not forget to click on Apply after changing compilation version.

A beginner : How to identify errors in selenium webdriver [duplicate]

This question already has answers here:
java.lang.Error: Unresolved compilation problems : WebDriver/ChromeDriver cannot be resolved to a type error while executing selenium tests
(5 answers)
Closed 3 years ago.
Question is:
1) In my simple program how do I identify errors in each line before run it?
2) I placed my program here, while running I am getting many errors. How can I resolve them?
Program:
package newpackage;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Myclass {
public static void main(String[] args) {
System.out.println("Chrome is selected");
System.setProperty("webdriver.chrome.driver","C:\\ProgramFiles\\Chrome65.0.3325.146\\googlechromeportable.exe");
WebDriver driver= new ChromeDriver();
driver.get("https://www.facebook.com/");
driver.manage().window().maximize();
//XPath for Email Field
driver.findElement(By.xpath("//*[#id='login']")).sendKeys("xxx#gmail.com");
//XPath for Password Field
//driver.findElement(By.xpath("//*[#id='pass']")).sendKeys("xxxxxxx");
driver.findElement(By.xpath("//*[#id=\"u_0_a\"]")).click();
}
}
Error:

You need to specify the driver location , by mistake you gave the browser.exe path so kindly modify your code as below . My chromedriverexe in Jar_files folder and you may need to download it and place it there . I advise you to refer a blog or a video prior to scripting so that you can get more clear idea.
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.testng.Assert;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
public class ExecutionbasedOnTReachabilityOfSite {
WebDriver driver;
#BeforeClass()
public void setUp() throws IOException {
System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + "\\Jar_files\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
// To start Chrome in Maximized browser window
options.addArguments("start-maximized");
// To remove Chrome is being controlled by automated test software
options.addArguments("disable-infobars");
driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
}

It is because you have not added selenium-server-standalone-3.141.59.jar as dependency in build path.
Download JAR from below path:
https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar
Right click on Project Folder > Build Path > Configure Build Path > Select & Add downloaded external JAR
All compile time errors that you are getting will be resolved.

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");
