**`capitalize`** is a static method of the `StringUtils` class that is used to convert the *first character* of the given string to title case as per [Character.toTitleCase](https://www.educative.io/answereditor/6198390204923904). The remaining characters of the string are not changed.

For example:
  
---
    string = "ababaaaabbbcccac"
---

`capitalize` returns `Ababaaaabbbcccac`, changing the case of the first character to title case.

# 
#  Add apache commons-lang package

`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).

##
## Import `StringUtils`

You can import the `StringUtils` class as follows.

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

# 
#  Syntax

---
```
public static String capitalize(final String str)
```
---

# 
## Parameters

`final String str` is the string to be capitalized.

##
## Returns

The method `capitalize()` returns the capitalized string.

import org.apache.commons.lang3.StringUtils;

public class Main {

    public static void main(String[] args) {
        System.out.println(StringUtils.capitalize("ababaaaabbbcccac"));
        System.out.println(StringUtils.capitalize("'hello'"));
    }
}

#
