Java实现判断浏览器版本与类型简单代码示例

public static void main(String[] args) {
	String agent=request.getHeader("User-Agent").toLowerCase();
	System.out.println(agent);
	System.out.println("浏览器版本："+getBrowserName(agent));
}
public String getBrowserName(String agent) {
	if(agent.indexOf("msie 7")>0){
		return "ie7";
	} else if(agent.indexOf("msie 8")>0){
		return "ie8";
	} else if(agent.indexOf("msie 9")>0){
		return "ie9";
	} else if(agent.indexOf("msie 10")>0){
		return "ie10";
	} else if(agent.indexOf("msie")>0){
		return "ie";
	} else if(agent.indexOf("opera")>0){
		return "opera";
	} else if(agent.indexOf("opera")>0){
		return "opera";
	} else if(agent.indexOf("firefox")>0){
		return "firefox";
	} else if(agent.indexOf("webkit")>0){
		return "webkit";
	} else if(agent.indexOf("gecko")>0 && agent.indexOf("rv:11")>0){
		return "ie11";
	} else{
		return "Others";
	}
}

public final static String[] agent = { "Android", "iPhone", "iPod","iPad", "Windows Phone", "MQQBrowser" };
public static Boolean checkAgentIsMobile(String ua) {
	Boolean flag = false;
	if (!ua.contains("Windows NT") || (ua.contains("Windows NT") && ua.contains("compatible; MSIE 9.0;"))) {
