**`uncapitalize`** is a static method of the `StringUtils` class that is used to convert the first character of the given string to lowercase, as per [Character.toLowerCase](https://www.educative.io/answers/what-is-charactertolowercase-in-java). The remaining characters of the string are not changed.

For example:
  
```java
string = "AbaBAaaabBbCCcaC"
```

`uncapitalize` returns `abaBAaaabBbCCcaC`, changing the case of the first character to lowercase.

`StringUtils` is defined in the `Apache Commons Lang` package. `Apache Commons Lang` can be added to the Maven project by adding the following dependency to the `pom.xml` file.

```xml
<dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>3.12.0</version>
</dependency>
```

> Note: For other versions of the commons-lang package, refer to the [Maven Repository](https://mvnrepository.com/artifact/org.apache.commons/commons-lang3).

You can import the `StringUtils` class as follows:

```java
import org.apache.commons.lang3.StringUtils;
```

#     
#  Syntax

```
public static String uncapitalize(final String str)
```

# 
## Parameters
* `final String str`: the string to be uncapitalized

##
## Return value
This returns an uncapitalized string.

import org.apache.commons.lang3.StringUtils;

public class Main {

    public static void main(String[] args) {
        System.out.println(StringUtils.uncapitalize("AbaBAaaabBbCCcaC"));
        System.out.println(StringUtils.uncapitalize("'hello'"));
    }
}

#       
## Output

```terminal
abaBAaaabBbCCcaC
'hello'
```

The second string remains the same as the input string because the first character is in single quotes.
