[FIXED] Chromedriver: How to translate a page using selenium?

Issue

I need to translate a page from Japanese to English, using selenium in chrome browser. I tried different ways one of sample code snippet is as following

import java.util.concurrent.TimeUnit;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
public class Main {

    private WebDriver driver=null;
    WebDriverLoad a;

    @Test
    public void successfulDesignerLogin() throws Exception{
//      final DesiredCapabilities capabilities = DesiredCapabilities.chrome();
//        capabilities.setJavascriptEnabled(true);
        String chromedriver =  "/dev/Saved/chromedriver";
        System.setProperty("webdriver.chrome.driver",chromedriver);

        ChromeOptions options = new ChromeOptions();
        options.addArguments("--lang=en-ca");
        //Map<String, Object> prefs = new HashMap<String, Object>();
        //prefs.put("intl.accept_languages", "en,en_US");
        //options.setExperimentalOption("prefs", prefs);


       ChromeDriver driver = new ChromeDriver(options);
       driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS);
       driver.get("https://www.bbc.com/japanese");
       driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
       driver.close();


}
}

I tried a couple of solution options.addArguments options.setExperimentalOption but nothing works can any one suggests me what can be the solution

Solution

You need to enable translate and add target language ID to the whitelist {"from" : "to"}.

"translate":{"enabled":"true"}
"translate_whitelists": {"ja":"en"}

in java:

Map<String, Object> prefs = new HashMap<String, Object>();
Map<String, Object> langs = new HashMap<String, Object>();
langs.put("ja", "en");
prefs.put("translate", "{'enabled' : true}");
prefs.put("translate_whitelists", langs);
options.setExperimentalOption("prefs", prefs);
