> Here are some initial ideas:
>
>
> 1. *findAllOccurrences(String str, String subStr)*
> - Description: Returns a list of all indexes where a substring occurs in
> the main string.
> - Example: findAllOccurrences("abcabc", "a") → [0, 3]
>
> 2. *toTitleCase(String str)*
> - Description: Converts each word's first character to uppercase and the
> rest to lowercase.
> - Example: toTitleCase("hello world") → "Hello World"
>
> 3. *smartTruncate(String str, int maxLength)*
> - Description: Truncates the string to the nearest full word under the
> limit and appends "..." if needed.
> - Example: smartTruncate("This is a long sentence", 10) → "This is..."
>
> 4. *removeRepeatedCharacters(String str)*
> - Description: Removes consecutive duplicate characters.
> - Example: removeRepeatedCharacters("aaabbbcccaaa") → "abca"
>
> 5. *isTitleCase(String str)*
> - Description: Checks if the input is in title case format.
> - Example: isTitleCase("Hello World") → true
>
> 6. *countWords(String str)*
> - Description: Returns the number of words in the input string.
> - Example: countWords("Apache Commons Lang") → 3
>
>
> I’d be happy to implement these methods and write appropriate JUnit tests.
> If the community finds these valuable, I can create a JIRA issue and start
> working on the patch.
Thanks for your interest in contributing to "Commons".
> Looking forward to your feedback!
Your proposed utilities seem better suited to [Text] than [Lang].
