You can create an instance of ChromeOptions, which has convenient methods for setting ChromeDriver-specific capabilities. You can then pass the ChromeOptions object into the ChromeDriver constructor:
Below is the code:
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
ChromeOptions options = new ChromeOptions();
capabilities.setCapability("chrome.binary", "<Path to binary>");
webDriver = new ChromeDriver(capabilities);
Hope this helps!
