I'm using the following function to get video IDs from YouTube URLs.
static String getVideoIdFromUrl(String url) {
String regex = "http(?:s)?://(?:www\\.)?youtu(?:\\.be/|be\\.com/(?:watch\\?v=|v/\u200C\u200B|embed/|user/(?:[\\w#\u200C\u200B]+/)+))([^&#?\\n]+)";
String id = null;
Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(url);
if (matcher.matches()) {
id = matcher.group(1);
}
return id;
}
This works for getting the video ID for almost all formats. However, it returns null when provided with URLs with a timestamp.

How do I write a function that returns both the video ID and the timestamp?
You can't return multiple variables in java, however you could load both the id and time into a HashMap and return that. It might look something like the following:
static Map<String,String> getVideoIdFromUrl(String url) {
// PATTERN
String regex = "v=([^#&\n\r]+)|t=([^#&\n\r]+)";
// INIT RETURN DATA
String id = "";
String time = "";
// RUN REGEX
Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(url);
// CHECK
while (matcher.find()) {
// SET ID
if(matcher.group(1) != null)
id = matcher.group(1);
// SET TIME
if(matcher.group(2) != null)
time = matcher.group(2);
}
// BUILD RETURN DATA
Map<String,String> returnData = new HashMap<String, String>();
returnData.put("id", id);
returnData.put("time", time);
// RETURN
return returnData;
}
I ran this function with the following output:
// RUN FUNCTION
Map<String,String> returnMap = myObject.getVideoIdFromUrl("http://www.youtube.com/watch?v=0zM4nApSvMg#t=0m10s");
// PRINT OUTPUT
System.out.println(returnMap);
// PRINTS:
// {id=0zM4nApSvMg, time=0m10s}
String urlid="" ;
String url="http://www.youtube.com/watch?v=0zM4nApSvMg#t=0m10s";
Pattern pattern = Pattern.compile("(?:http|https|)(?::\\/\\/|)(?:www.|)(?:youtu\\.be\\/|youtube\\.com(?:\\/embed\\/|\\/v\\/|\\/watch\\?v=|\\/ytscreeningroom\\?v=|\\/feeds\\/api\\/videos\\/|\\/user\\\\S*[^\\w\\-\\s]|\\S*[^\\w\\-\\s]))([\\w\\-\\_]{11})[a-z0-9;:##?&%=+\\/\\$_.-]*");
Matcher result = pattern.matcher(url);
if (result.find())
{
urlid=result.group(1);
}
This matches almost all youtube urls.

I have a text file in json, and I want to replace NumberInt(x) with the number x.
In the text file, there are records/data which is in json that has a field workYear: NumberInt(2010) as an example.
I want to replace this into workYear: 2010 by removing NumberInt( and ).
This NumberInt(x) is located anywhere in text file and I want to replace all of it with its number.
I can search all the occurences of this, but I am not sure how to replace it with just the number value.
String json = <json-file-content>
String sPattern = "NumberInt\\([0-9]+\\)";
Pattern pattern = Pattern.compile(sPattern);
Matcher matcher = pattern.matcher(json);
while (matcher.find()) {
String s = matcher.group(0);
int workYear = Integer.parseInt(s.replaceAll("[^0-9]", ""));
System.out.println(workYear);
}
I would like to replace all the NumberInt(x) with just the number value int json String... then I will update the text file (json file).
Thanks!
Following should work. You need to capture the tokens.
String json = "workYear:NumberInt(2010) workYear:NumberInt(2011)";
String sPattern = "NumberInt\\(([0-9]+)\\)";
Pattern pattern = Pattern.compile(sPattern);
Matcher matcher = pattern.matcher(json);
List<String> numbers = new ArrayList<>();
while (matcher.find()) {
String s = matcher.group(1);
numbers.add(s);
}
for (String number: numbers) {
json = json.replaceAll(String.format("NumberInt\\(%s\\)", number), number);
}
System.out.println(json);
You could build the output using a StringBuilder like below,
Please refer to JavaDoc for appendReplacement for info on how this works.
String s = "workYear: NumberInt(2010)\nworkYear: NumberInt(2012)";
String sPattern = "NumberInt\\([0-9]+\\)";
Pattern pattern = Pattern.compile(sPattern);
Matcher matcher = pattern.matcher(s);
StringBuilder sb = new StringBuilder();
while (matcher.find()) {
String s2 = matcher.group(0);
int workYear = Integer.parseInt(s2.replaceAll("[^0-9]", ""));
matcher.appendReplacement(sb, String.valueOf(workYear));
}
matcher.appendTail(sb);
String result = sb.toString();
I have the follow urls.
https://docs.google.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY/edit#gid=1842172258
https://docs.google.com/a/example.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6PTKTzY0xOM5c6TXY/edit#gid=1842172258
https://docs.google.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY
Foreach url, I need to extract the sheet id: 1mrsetjgfZI2BIypz7SGHMOfHGv6PTKTzY0xOM5c6TXY into a java String.
I am thinking of using split but it can't work with all test cases:
String string = "https://docs.google.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY/edit#gid=1842172258";
String[] parts = string.split("/");
String res = parts[parts.length-2];
Log.d("hello res",res );
How can I that be possible?
You can use regex \/d\/(.*?)(\/|$) (regex demo) to solve your problem, if you look closer you can see that the ID exist between d/ and / or end of line for that you can get every thing between this, check this code demo :
String[] urls = new String[]{
"https://docs.google.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY/edit#gid=1842172258",
"https://docs.google.com/a/example.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6PTKTzY0xOM5c6TXY/edit#gid=1842172258",
"https://docs.google.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY"
};
String regex = "\\/d\\/(.*?)(\\/|$)";
Pattern pattern = Pattern.compile(regex);
for (String url : urls) {
Matcher matcher = pattern.matcher(url);
while (matcher.find()) {
System.out.println(matcher.group(1));
}
}
Outputs
1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY
1mrsetjgfZI2BIypz7SGHMOfHGv6PTKTzY0xOM5c6TXY
1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY
it looks like the id you are looking for always follow "/spreadsheets/d/" if it is the case you can update your code to that
String string = "https://docs.google.com/spreadsheets/d/1mrsetjgfZI2BIypz7SGHMOfHGv6kTKTzY0xOM5c6TXY/edit#gid=1842172258";
String[] parts = string.split("spreadsheets/d/");
String result;
if(parts[1].contains("/")){
String[] parts2 = parts[1].split("/");
result = parts2[0];
}
else{
result=parts[1];
}
System.out.println("hello "+ result);
Using regex
Pattern pattern = Pattern.compile("(?<=\\/d\\/)[^\\/]*");
Matcher matcher = pattern.matcher(url);
System.out.println(matcher.group(1));
Using Java
String result = url.substring(url.indexOf("/d/") + 3);
int slash = result.indexOf("/");
result = slash == -1 ? result
: result.substring(0, slash);
System.out.println(result);
Google use fixed lenght characters for its IDs, in your case they are 44 characters and these are the characters google use: alphanumeric, -, and _ so you can use this regex:
regex = "([\w-]){44}"
match = re.search(regex,url)
I would like to have link from the share intent. When I receive a link via chrome its properly formatted, but sometimes other apps add text too.
Example:
Chrome: "www.recode.net/2016/7/21/12243560/google-machine-learning-comics-play"
Twitter: "Guys check out this link it's so cool https://www.recode.net/2016/7/21/12243560/google-machine-learning-comics-play"
So in case of twitter I would like to get rid of all the context and have only the link remaining,ie, www.recode.net/2016/7/21/12243560/google-machine-learning-comics-play
Note: Link may be of any format https://.. (or) www. .. (or) recode.net/... (without the www at the beginning).
Any regex to sort this out?
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shareintent);
// Get intent, action and MIME type
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
if (Intent.ACTION_SEND.equals(action) && type != null)
{
if ("text/plain".equals(type))
{
// Handle text being sent
handleSendText(intent);
}
}
}
void handleSendText(Intent intent)
{
String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
if (sharedText != null)
{
// Update UI to reflect text being shared
TextView tvShare = (TextView) findViewById(R.id.tvShare);
tvShare.setText(sharedText);
}
}
The following method does the trick:
//Pull all links from the body for easy retrieval
public ArrayList<String> pullLinks(String text)
{
ArrayList<String> links = new ArrayList<String>();
//String regex = "\\(?\\b(http://|www[.])[-A-Za-z0-9+&##/%?=~_()|!:,.;]*[-A-Za-z0-9+&##/%=~_()|]";
String regex = "\\(?\\b(https?://|www[.]|ftp://)[-A-Za-z0-9+&##/%?=~_()|!:,.;]*[-A-Za-z0-9+&##/%=~_()|]";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(text);
while(m.find())
{
String urlStr = m.group();
if (urlStr.startsWith("(") && urlStr.endsWith(")"))
{
urlStr = urlStr.substring(1, urlStr.length() - 1);
}
links.add(urlStr);
}
return links;
}
You could recognize and extract a particular pattern from the String.
// Pattern for recognizing a URL, based off RFC 3986
private static final Pattern urlPattern = Pattern.compile(
"(?:^|[\\W])((ht|f)tp(s?):\\/\\/|www\\.)"
+ "(([\\w\\-]+\\.){1,}?([\\w\\-.~]+\\/?)*"
+ "[\\p{Alnum}.,%_=?&#\\-+()\\[\\]\\*$~#!:/{};']*)",
Pattern.CASE_INSENSITIVE | Pattern.MULTILINE | Pattern.DOTALL);
Example :
Matcher matcher = urlPattern.matcher("foo bar http://example.com baz");
while (matcher.find()) {
int matchStart = matcher.start(1);
int matchEnd = matcher.end();
// now you have the offsets of a URL match
}
reference: may be other answers there will be useful to you as well
You can just extract the Url from a string using the Matcher Class.following code will extract all the links included in the string to an array of Urls.
Matcher webMatcher = Patterns.WEB_URL.matcher(stringWhichContainsUrl);
ArrayList<String> hyperLinks = new ArrayList<>();
while (webMatcher.find()) {
String res = webMatcher.group();
hyperLinks.add(res);
}
Log.e("links", hyperLinks.toString());
There are input strings of the format
${ENC}:107ec5141234742beec5cb5b1917e2e6:{ENC}$${ENC}:d0b2ddf0b9e7b397558c20c623237c4f:{ENC}$${ENC}:85d6f3cd7dcc5c67cad68ae45a0d5afc:{ENC}$${ENC}:5c0dfb55a843f830024df0d74993b668:{ENC}$
As you can see, the data ( in bold), are prefixed with ${ENC}: and suffixed with :{ENC}$. And i want to replace all the Strings in between them with processed data.
I am using the Regular Expression:
\$\{ENC\}\:(.*?)\:\{ENC\}\$
which after escaping for java:
\\$\\{ENC\\}\\:(.*?)\\:\\{ENC\\}\\$
to find the matches and replace the Strings.
My code sample is below:
String THE_REGEX = "\\$\\{ENC\\}\\:(.*?)\\:\\{ENC\\}\\$";
Pattern THE_PATTERN = Pattern.compile(THE_REGEX);
public static boolean isProcessingRequired(String data){
if(data == null){
return false;
}
return data.matches(THE_REGEX);
}
public String getProcessedString(String dataString){
Matcher matcher = THE_PATTERN.matcher(dataString);
if(matcher.matches()){
String processedData = null;
String dataItem = matcher.group(1);
String procItem = doSomeProcessing(dataItem);
processedData = dataString.replaceAll("\\$\\{ENC\\}:" + encData + ":\\{ENC\\}\\$", procItem);
if(isProcessingRequired(processedData)){
processedData = getProcessedString(processedData);
}
return processedData;
} else {
return dataString;
}
}
public String doSomeProcessing(String str){
// do some processing on the string
// for now:
str = "DONE PROCESSING!!"
return str;
}
But at matcher.group(1), I'm getting
107ec5141234742beec5cb5b1917e2e6:ENC}$${ENC}:d0b2ddf0b9e7b397558c20c623237c4f:{ENC}$${ENC}:85d6f3cd7dcc5c67cad68ae45a0d5afc:{ENC}$${ENC}:5c0dfb55a843f830024df0d74993b668
instead of
107ec5141234742beec5cb5b1917e2e6
which I was expecting.
I'm using the ? in regex to avoid this problem.
And when I tried it at the www.regexe.com, regex appears to be fine
What am I doing wrong here?
The problem is that you are using Matcher.matches() instead of Matcher.find().
From the javadoc:
public boolean matches()
Attempts to match the entire region against the pattern.
public boolean find()
Attempts to find the next subsequence of the input sequence that matches the pattern.
Here is a simple code expliciting the difference :
Matcher matcher = Pattern.compile("\\Q${ENC}\\E(.*?)\\Q{ENC}$\\E").matcher("${ENC}1{ENC}$${ENC}2{ENC}$");
if (matcher.matches()) {
System.out.println(matcher.group(1)); // Will print "1{ENC}$${ENC}2"
}
matcher.reset();
if (matcher.find()) {
System.out.println(matcher.group(1)); // Will print "1"
}

JavaScript REGEX: How do I get the YouTube video id from a URL?
Figured this question wasn't here for Java, in case you need to do it in Java here's a way
public static String extractYTId(String ytUrl) {
String vId = null;
Pattern pattern = Pattern.compile(
"^https?://.*(?:youtu.be/|v/|u/\\w/|embed/|watch?v=)([^#&?]*).*$",
Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(ytUrl);
if (matcher.matches()){
vId = matcher.group(1);
}
return vId;
}
Works for URLs like (also for https://...)

Previous answers don't work for me.. It's correct method. It works with www.youtube.com and youtu.be links.
private String getYouTubeId (String youTubeUrl) {
String pattern = "(?<=youtu.be/|watch\\?v=|/videos/|embed\\/)[^#\\&\\?]*";
Pattern compiledPattern = Pattern.compile(pattern);
Matcher matcher = compiledPattern.matcher(youTubeUrl);
if(matcher.find()){
return matcher.group();
} else {
return "error";
}
}

Note: Using regex match group(1) to get ID
public static String getVideoId(#NonNull String videoUrl) {
String videoId = "";
String regex = PLEASE_COPY_ABOVE_REGEX_PATTERN
Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(url);
if(matcher.find()){
videoId = matcher.group(1);
}
return videoId;
}
To me, for the sample links you posted, this regex looks more precise (capturing the ID to Group 1):
https?://(?:www\.)?youtu(?:\.be/|be\.com/(?:watch\?v=|v/|embed/|user/(?:[\w#]+/)+))([^&#?\n]+)
On the demo, see the capture groups in the bottom right pane. However, for the second match, not entirely sure that this is a correct ID as it looks different from the other samples—to be tweaked if needed.
In code, something like:
Pattern regex = Pattern.compile("http://(?:www\\.)?youtu(?:\\.be/|be\\.com/(?:watch\\?v=|v/|embed/|user/(?:[\\w#]+/)+))([^&#?\n]+)");
Matcher regexMatcher = regex.matcher(subjectString);
if (regexMatcher.find()) {
VideoID = regexMatcher.group(1);
}
private fun extractVideoId(ytUrl: String?): String? {
var videoId: String? = null
val regex =
"^((?:https?:)?//)?((?:www|m)\\.)?((?:youtube\\.com|youtu.be|youtube-nocookie.com))(/(?:[\\w\\-]+\\?v=|feature=|watch\\?|e/|embed/|v/)?)([\\w\\-]+)(\\S+)?\$"
val pattern: Pattern = Pattern.compile(
regex ,
Pattern.CASE_INSENSITIVE
)
val matcher: Matcher = pattern.matcher(ytUrl)
if (matcher.matches()) {
videoId = matcher.group(5)
}
return videoId
}
The above function with regex can extract video Id from

Tried the other ones but failed in my case - adjusted the regex to fit for my urls
public static String extractYoutubeVideoId(String ytUrl) {
String vId = null;
String pattern = "(?<=watch\\?v=|/videos/|embed\\/)[^#\\&\\?]*";
Pattern compiledPattern = Pattern.compile(pattern);
Matcher matcher = compiledPattern.matcher(ytUrl);
if(matcher.find()){
vId= matcher.group();
}
return vId;
}
This one works for below url's

Hope it will help some one. Thanks
Using regex from Tấn Nguyên:
public String getVideoIdFromYoutubeUrl(String url){
String videoId = null;
String regex = "http(?:s)?:\\/\\/(?:m.)?(?:www\\.)?youtu(?:\\.be\\/|be\\.com\\/(?:watch\\?(?:feature=youtu.be\\&)?v=|v\\/|embed\\/|user\\/(?:[\\w#]+\\/)+))([^&#?\\n]+)";
Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(url);
if(matcher.find()){
videoId = matcher.group(1);
}
return videoId;
}
Credit to Tấn Nguyên.
This will work for me and simple..
public static String getVideoId(#NonNull String videoUrl) {
String reg = "(?:youtube(?:-nocookie)?\\.com\\/(?:[^\\/\\n\\s]+\\/\\S+\\/|(?:v|e(?:mbed)?)\\/|\\S*?[?&]v=)|youtu\\.be\\/)([a-zA-Z0-9_-]{11})";
Pattern pattern = Pattern.compile(reg, Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(videoUrl);
if (matcher.find())
return matcher.group(1);
return null;
}
Just pass youtube link in below function , it will detect all type of youtube url
public static String getYoutubeID(String youtubeUrl) {
if (TextUtils.isEmpty(youtubeUrl)) {
return "";
}
String video_id = "";
String expression = "^.*((youtu.be" + "\\/)" + "|(v\\/)|(\\/u\\/w\\/)|(embed\\/)|(watch\\?))\\??v?=?([^#\\&\\?]*).*"; // var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#\&\?]*).*/;
CharSequence input = youtubeUrl;
Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(input);
if (matcher.matches()) {
String groupIndex1 = matcher.group(7);
if (groupIndex1 != null && groupIndex1.length() == 11)
video_id = groupIndex1;
}
if (TextUtils.isEmpty(video_id)) {
if (youtubeUrl.contains("youtu.be/") ) {
String spl = youtubeUrl.split("youtu.be/")[1];
if (spl.contains("\\?")) {
video_id = spl.split("\\?")[0];
}else {
video_id =spl;
}
}
}
return video_id;
}
Combining a couple of methods, to cover as many formats as possible, is recommended.
String ID1 = getYoutubeID1(url); regex 1
String ID2 = getYoutubeID2(url); regex 2
String ID3 = getYoutubeID3(url); regex 3
then, using an if/switch statement to choose a value that isn't null and is valid.
I actully try all the above but some times work and some times fail
any way I found this may it help -- in this site
private final static String expression = "(?<=watch\\?v=|/videos/|embed\\/|youtu.be\\/|\\/v\\/|\\/e\\/|watch\\?v%3D|watch\\?feature=player_embedded&v=|%2Fvideos%2F|embed%\u200C\u200B2F|youtu.be%2F|%2Fv%2F)[^#\\&\\?\\n]*";
public static String getVideoId(String videoUrl) {
if (videoUrl == null || videoUrl.trim().length() <= 0){
return null;
}
Pattern pattern = Pattern.compile(expression);
Matcher matcher = pattern.matcher(videoUrl);
try {
if (matcher.find())
return matcher.group();
} catch (ArrayIndexOutOfBoundsException ex) {
ex.printStackTrace();
}
return null;
}

This will work on two kinks of youtube video urls either direct or shared URL.
Direct url: https://www.youtube.com/watch?v=XXXXXXXXXXX
Shared url: https://youtu.be/XXXXXXXXXXX
This is very similar to the link posted in your question.
String url = "https://www.youtube.com/watch?v=wZZ7oFKsKzY";
if(url.indexOf("v=") == -1) //there's no video id
return "";
String id = url.split("v=")[1]; //everything before the first 'v=' will be the first element, i.e. [0]
int end_of_id = id_to_end.indexOf("&"); //if there are other parameters in the url, get only the id's value
if(end_index != -1)
id = url.substring(0, end_of_id);
return id;
Without regex :
String url - "https://www.youtube.com/watch?v=BYrumLBuzHk"
String video_id = url.replace("https://www.youtube.com/watch?v=", "")
So now you have a video ID in string video_id.
