Get IE Browser Version Using Java
The code below shows you the way to get the version of IE browser using Java. To do this, we simply look at User-Agent data (request.getHeader("User-Agent")) sent by the browser to determine whether the visitors are using IE browser.
IEBrowser.java
package com.bytenota;
import java.text.NumberFormat;
import java.text.ParseException;
import javax.servlet.http.HttpServletRequest;
public class IEBrowser {
public static Integer getIEVersion(HttpServletRequest request) {
String userAgent = request.getHeader("User-Agent");
try {
// detect IE below 11
if (userAgent.contains("MSIE")) {
String[] parts = userAgent.split("MSIE");
int version = NumberFormat.getInstance().parse(parts[1]).intValue();
return version;
}
// detect IE 11
if (userAgent.contains("Trident/")) {
String[] parts = userAgent.split("rv:");
int version = NumberFormat.getInstance().parse(parts[1]).intValue();
return version;
}
} catch (ParseException ex) {
}
// not found
return null;
}
}
