The short answer is no. How to open Chrome Developer console in Selenium WebDriver using JAVA. As the provided link states you cannot directly access the chrome developer tools.

But if you are interested in access the contents of the browser console and network tab, selenium provides you a way.

System.setProperty("webdriver.chrome.driver", getChromeDriverLocation());

LoggingPreferences loggingprefs = new LoggingPreferences();
loggingprefs.enable(LogType.BROWSER, Level.WARNING);
loggingprefs.enable(LogType.PERFORMANCE, Level.WARNING);

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(CapabilityType.LOGGING_PREFS, loggingprefs);

driver = new ChromeDriver(capabilities);

You can then print the logs as needed

LogEntries logEntries = SeleniumBaseTest.getWebDriver().manage().logs()
            .get(org.openqa.selenium.logging.LogType.BROWSER);
for (LogEntry entry : logEntries) {
    System.out.println((String.format("%s %s %s\n", new Date(entry.getTimestamp()), entry.getLevel(),
                entry.getMessage())));
}

LogType.BROWSER will give you the browser console. Logtype.PERFROMANCE will give you the network tab.

Other ways to access the network tab is to use a browser proxy to record the transactions. http://www.seleniumeasy.com/selenium-tutorials/browsermob-proxy-selenium-example
