What is the WordUtils.initials method in Java?
initials is a static method of the WordUtils class that is used to get the initial character from each word in a given string. The method optionally takes in a list of delimiters to determine the words in the given string. If no delimiters are specified, the default delimiter used is whitespace.
WordUtils is defined in the Apache Commons Text package. Apache Commons Text can be added to the Maven Project by adding the following dependency to the pom.xml file.
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-text</artifactId>
<version>1.9</version>
</dependency>
For other versions of the
commons-textpackage, refer to the Maven Repository.
You can import the WordUtils class as follows:
import org.apache.commons.text.WordUtils;
Syntax
public static String initials(final String str, final char... delimiters)
Parameters
final String str: stringfinal char... delimiters: set of delimiters to determine words from the given string
Return value
The method returns initials as a string.
Code
import org.apache.commons.text.WordUtils;public class Main {public static void main(String[] args) {String string = "Hello educative how are you?";System.out.println("Original String - " + string);System.out.println("Initials - " + WordUtils.initials(string));System.out.println();string = "Hello educative,how are you?";System.out.println("Original String - " + string);System.out.println("Initials - " + WordUtils.initials(string, ','));}}
Explanation
- string = “Hello educative how are you?”
The method returns Hehay. The output string contains the initial character of every word delimited by whitespace.
- string = “Hello educative,how are you?”
The method returns Hh. The output string contains the initial character of every word delimited by a comma. There are two words where the comma is considered the delimiter.
Expected output
Original String - Hello educative how are you?
Initials - Hehay
Original String - Hello educative,how are you?
Initials - Hh
