The missing emoji library for java.

emoji-java is a lightweight java library that helps you use Emojis in your java applications.

<dependency> <groupId>com.vdurmont</groupId> <artifactId>emoji-java</artifactId> <version>4.0.0</version> </dependency>

You can also download the project, build it with mvn clean install and add the generated jar to your buildpath.

compile 'com.vdurmont:emoji-java:4.0.0'

• Use releases tab to download the jar directly.
• Download JSON-java dependency from http://mvnrepository.com/artifact/org.json/json.

The EmojiManager provides several static methods to search through the emojis database:

• getForTag returns all the emojis for a given tag
• getForAlias returns the emoji for an alias
• getAll returns all the emojis
• isEmoji checks if a string is an emoji

You can also query the metadata:

• getAllTags returns the available tags

Or get everything:

• getAll returns all the emojis

An Emoji is a POJO (plain old java object), which provides the following methods:

• getUnicode returns the unicode representation of the emoji
• getUnicode(Fitzpatrick) returns the unicode representation of the emoji with the provided Fitzpatrick modifier. If the emoji doesn't support the Fitzpatrick modifiers, this method will throw an UnsupportedOperationException. If the provided Fitzpatrick is null, this method will return the unicode of the emoji.
• getDescription returns the (optional) description of the emoji
• getAliases returns a list of aliases for this emoji
• getTags returns a list of tags for this emoji
• getHtmlDecimal returns an html decimal representation of the emoji
• getHtmlHexadecimal returns an html decimal representation of the emoji
• supportsFitzpatrick returns true if the emoji supports the Fitzpatrick modifiers, else false

Some emojis now support the use of Fitzpatrick modifiers that gives the choice between 5 shades of skin tones:

We defined the format of the aliases including a Fitzpatrick modifier as:

:ALIAS|TYPE: 

A few examples:

:boy|type_1_2: :swimmer|type_4: :santa|type_6: 

To replace all the aliases and the html representations found in a string by their unicode, use EmojiParser#parseToUnicode(String).

For example:

Stringstr = "An :grinning:awesome :smiley:string 😄with a few :wink:emojis!"; Stringresult = EmojiParser.parseToUnicode(str); System.out.println(result); // Prints:// "An 😀awesome 😃string 😄with a few 😉emojis!"

To replace all the emoji's unicodes found in a string by their aliases, use EmojiParser#parseToAliases(String).

For example:

Stringstr = "An 😀awesome 😃string with a few 😉emojis!"; Stringresult = EmojiParser.parseToAliases(str); System.out.println(result); // Prints:// "An :grinning:awesome :smiley:string with a few :wink:emojis!"

By default, the aliases will parse and include any Fitzpatrick modifier that would be provided. If you want to remove or ignore the Fitzpatrick modifiers, use EmojiParser#parseToAliases(String, FitzpatrickAction). Examples:

Stringstr = "Here is a boy: \uD83D\uDC66\uD83C\uDFFF!"; System.out.println(EmojiParser.parseToAliases(str)); System.out.println(EmojiParser.parseToAliases(str, FitzpatrickAction.PARSE)); // Prints twice: "Here is a boy: :boy|type_6:!"System.out.println(EmojiParser.parseToAliases(str, FitzpatrickAction.REMOVE)); // Prints: "Here is a boy: :boy:!"System.out.println(EmojiParser.parseToAliases(str, FitzpatrickAction.IGNORE)); // Prints: "Here is a boy: :boy:🏿!"

To replace all the emoji's unicodes found in a string by their html representation, use EmojiParser#parseToHtmlDecimal(String) or EmojiParser#parseToHtmlHexadecimal(String).

For example:

Stringstr = "An 😀awesome 😃string with a few 😉emojis!"; StringresultDecimal = EmojiParser.parseToHtmlDecimal(str); System.out.println(resultDecimal); // Prints:// "An 😀awesome 😃string with a few 😉emojis!"StringresultHexadecimal = EmojiParser.parseToHtmlHexadecimal(str); System.out.println(resultHexadecimal); // Prints:// "An 😀awesome 😃string with a few 😉emojis!"

By default, any Fitzpatrick modifier will be removed. If you want to ignore the Fitzpatrick modifiers, use EmojiParser#parseToAliases(String, FitzpatrickAction). Examples:

Stringstr = "Here is a boy: \uD83D\uDC66\uD83C\uDFFF!"; System.out.println(EmojiParser.parseToHtmlDecimal(str)); System.out.println(EmojiParser.parseToHtmlDecimal(str, FitzpatrickAction.PARSE)); System.out.println(EmojiParser.parseToHtmlDecimal(str, FitzpatrickAction.REMOVE)); // Print 3 times: "Here is a boy: 👦!"System.out.println(EmojiParser.parseToHtmlDecimal(str, FitzpatrickAction.IGNORE)); // Prints: "Here is a boy: 👦🏿!"

The same applies for the methods EmojiParser#parseToHtmlHexadecimal(String) and EmojiParser#parseToHtmlHexadecimal(String, FitzpatrickAction).

You can easily remove emojis from a string using one of the following methods:

• EmojiParser#removeAllEmojis(String): removes all the emojis from the String
• EmojiParser#removeAllEmojisExcept(String, Collection<Emoji>): removes all the emojis from the String, except the ones in the Collection
• EmojiParser#removeEmojis(String, Collection<Emoji>): removes the emojis in the Collection from the String

For example:

Stringstr = "An 😀awesome 😃string with a few 😉emojis!"; Collection<Emoji> collection = newArrayList<Emoji>(); collection.add(EmojiManager.getForAlias("wink")); // This is 😉System.out.println(EmojiParser.removeAllEmojis(str)); System.out.println(EmojiParser.removeAllEmojisExcept(str, collection)); System.out.println(EmojiParser.removeEmojis(str, collection)); // Prints:// "An awesome string with a few emojis!"// "An awesome string with a few 😉emojis!"// "An 😀awesome 😃string with a few emojis!"

You can search a string of mixed emoji/non-emoji characters and have all of the emoji characters returned as a Collection.

• EmojiParser#extractEmojis(String): returns all emojis as a Collection. This will include duplicates if emojis are present more than once.

emoji-java originally used the data provided by the github/gemoji project. It is still based on it but has evolved since.

Here is a table of the available emojis and their aliases.
