In python, the string has a function called title, which makes a text look like a title. Does it have a function like this in Java? If not, how to do it?
Example: "Hi, my name is Goku". title() -> "Hi, My Name Is Goku"
I need that function because I’m working with people’s names, and the person’s name has to stay that way.
Another Example: Freight Freight Astrobalda -> Freight Forwardrotilda Astrobalda

The library Apache Commons Lang has the function capitalize in class Wordutils.
String title = WordUtils.capitalize("oi, meu nome é goku");
If you need to normalize a title beyond the first letter there is also the function capitalizeFully.
String title = WordUtils.capitalizeFully("oi, meu nOME é gOKU");

Is there a method that already comes in Java? Or, you know how to do this function?
As far as I know there is no method in the API itself, creating the method is very soft: basically making a split in String and capitalize on the first letter of each resulting word, then concatenate them again. But with a library you gain robustness (never re-invent the wheel). If you want to see how Apache implemented this method at a glance in the source code class.
