What is WordUtils.uncapitalize in Java?
uncapitalize is a static method of the WordUtils class that is used to uncapitalize all delimiter separated words in a string. Each word’s initial character is the only character that is altered.
Note:
- The set of delimiters that separate the words can be passed to the method.
- If no delimiters are specified, then the whitespace is considered the delimiter by default.
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-text package, refer to the Maven Repository.
You can import the WordUtils class as follows:
import org.apache.commons.text.WordUtils;
Syntax
public static String uncapitalize(final String str, final char... delimiters)
Parameters
final String str- string to be capitalizedfinal char... delimiters- set of delimiters

import org.apache.commons.text.WordUtils;public class Main {public static void main(String[] args) {String string = "Hello eduCATive,How ARe yOU?";System.out.print("Delimited by whitespace - ");System.out.print(WordUtils.uncapitalize(string));System.out.print("\nDelimited by comma (,) - ");System.out.print(WordUtils.uncapitalize(string, ','));}}
