ChromeOptions not getting applied - selenium-chromedriver

Question

I am trying to open the chrome browser with devtools open in maximized window.
Following code does not work, driver opens the URL in a smaller window without devtools.
System.setProperty("webdriver.chrome.driver", "<path to chrome.exe>");
ChromeOptions options = new ChromeOptions();
<String> chromeoptions = new ArrayList<String>();
chromeoptions.add("start-maximised");
chromeoptions.add("auto-open-devtools-for-tabs");
options.addArguments(chromeoptions);
WebDriver driver=new ChromeDriver(options);
driver.get("http://www.google.com");
I have also used Capabilities with no result.
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.binary", "<path to chrome exe>");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver=new ChromeDriver(capabilities);
I am using Chrome 75, selenium jar version 3.4.0
Any suggestion?

Answer 1

As per your code, there have some spelling mistake like("start-maximised") instead of ("--start-maximized")
kindly use the below code:
ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
options.addArguments("--auto-open-devtools-for-tabs");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver = new ChromeDriver(capabilities);

Try using chrome options like this. it'll download the correct chrome driver version automatically and also chrome options work correctly.
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option("detach", True)
chrome_options.add_argument("--start-maximized")
driver = webdriver.Chrome(ChromeDriverManager().install(), options=chrome_options)
driver.get('https://www.facebook.com/');
