Got a better solution from this link.

Use the following method to get the videoId from the link.

YoutubeHelper.java

import com.google.inject.Singleton; 

import java.util.regex.Matcher;
import java.util.regex.Pattern;

@Singleton 
public class YouTubeHelper { 

    final String youTubeUrlRegEx = "^(https?)?(://)?(www.)?(m.)?((youtube.com)|(youtu.be))/";
    final String[] videoIdRegex = { "\\?vi?=([^&]*)","watch\\?.*v=([^&]*)", "(?:embed|vi?)/([^/?]*)", "^([A-Za-z0-9\\-]*)"};

    public String extractVideoIdFromUrl(String url) {
        String youTubeLinkWithoutProtocolAndDomain = youTubeLinkWithoutProtocolAndDomain(url);

        for(String regex : videoIdRegex) {
            Pattern compiledPattern = Pattern.compile(regex);
            Matcher matcher = compiledPattern.matcher(youTubeLinkWithoutProtocolAndDomain);

            if(matcher.find()){
                return matcher.group(1);
            } 
        } 

        return null; 
    } 

    private String youTubeLinkWithoutProtocolAndDomain(String url) {
        Pattern compiledPattern = Pattern.compile(youTubeUrlRegEx);
        Matcher matcher = compiledPattern.matcher(url);

        if(matcher.find()){
            return url.replace(matcher.group(), "");
        } 
        return url;
    } 
} 

Hope this helps.
