How to set https proxy in selenium and chromedriver? Here is my code to set up http proxy.

        System.setProperty("webdriver.chrome.driver",
"C:\\Users\\lll\\Desktop\\chromedriver.exe");
        DesiredCapabilities cap = new DesiredCapabilities();
        Proxy proxy=new Proxy();
        String proxyIpAndPort= "123.123.123.123:31288";
        proxy.setHttpProxy(proxyIpAndPort).setFtpProxy(proxyIpAndPort).setSslProxy(proxyIpAndPort);
        cap.setCapability(CapabilityType.ForSeleniumServer.AVOIDING_PROXY, true);
        cap.setCapability(CapabilityType.ForSeleniumServer.ONLY_PROXYING_SELENIUM_TRAFFIC, true);
        cap.setCapability(CapabilityType.PROXY, proxy);
        driver = new ChromeDriver(cap);
