MS Edge: Unable to get browser version via Capabilities.getVersion() - selenium

Question

I have a Selenium project using Java that uses different browsers. I'm trying to introduce MS Edge, but having trouble using the getVersion() method from Capabilities. Below is a code snippet from a method that initializes the browser. WebDriver "driver" is declared at the beginning of the class.
if(strBrowser.equalsIgnoreCase("Edge"))
{
String FileName=m1.get("TOOLS_PATH").toString()+"//MicrosoftWebDriver.exe";
System.out.println("Full path to Edge executable: " + FileName);
File edgeDriver = new File(FileName);
System.setProperty("webdriver.edge.driver", edgeDriver.getAbsolutePath());
DesiredCapabilities caps = DesiredCapabilities.edge();
driver = new EdgeDriver(caps); //launches Edge browser
}
Capabilities caps = ((RemoteWebDriver) driver).getCapabilities();
String browserName = caps.getBrowserName();
String browserVersion = caps.getVersion().toString();
During debugging in ecliipse, when I hover on the 'caps' object after initializing it, it shows me the following:
Capabilities [{acceptSslCerts=true, browserVersion=25.10586.672.0, platformVersion=10, browserName=MicrosoftEdge, takesScreenshot=true, pageLoadStrategy=normal, takesElementScreenshot=true, platformName=windows, platform=ANY}]
The string browserName comes out to be "MicrosoftEdge", but browserVersion comes out empty. I'd expect that it'd come out to be "25.10586.672.0"

Try the below approach
String browser_version = null;
Capabilities cap = ((RemoteWebDriver) browserDriver).getCapabilities();
String browsername = cap.getBrowserName();
// This block to find out IE Version number
if ("internet explorer".equalsIgnoreCase(browsername)) {
String uAgent = (String) ((JavascriptExecutor) browserDriver).executeScript("return navigator.userAgent;");
System.out.println(uAgent);
//uAgent return as "MSIE 8.0 Windows" for IE8
if (uAgent.contains("MSIE") && uAgent.contains("Windows")) {
browser_version = uAgent.substring(uAgent.indexOf("MSIE")+5, uAgent.indexOf("Windows")-2);
} else if (uAgent.contains("Trident/7.0")) {
browser_version = "11.0";
} else {
browser_version = "0.0";
}
} else
{
//Browser version for Firefox and Chrome
browser_version = cap.getVersion();// .split(".")[0];
}
String browserversion = browser_version.substring(, browser_version.indexOf("."));
return browsername + " " + browserversion;

In firefox and Edge you need to specify the field name that you require its value - so please do like this:
Capabilities capabilities = ((RemoteWebDriver) webDriver).getCapabilities();
String browserVersion = capabilities.getCapability("browserVersion").toString();
