A public static method that when called and passed a $`$String$`$ must compute and return a $`$String$`$ value that contains just the capitalized first letter of each word.

Note: the arguments to this method will always be a $`$String$`$ containing one or more words, and the words will always be separated by a single space character, and a space character will always be followed by another word.

Hints:

The $`$indexOf$`$ method can be very helpful for finding things like space characters in a $`$String$`$

Java has an overloaded $`$indexOf$`$ method with takes an extra $`$int$`$ argument indicating where to start a search in a $`$String$`$

Java also has an $`$lastIndexOf$`$ method, which searches a $`$String$`$ starting at the end.

The $`$substring$`$ method can be very helpful for extracting one or more characters from a $`$String$`$

You may need to write some code to make decisions based on whether the input has one $($just first$),$ two $($first and last$),$ or three $($first$,$ middle, and last$)$ names.

A loop will definitely be useful.

It can be helpful to know and understand the difference between the $`$Scanner$`$ methods $`$next$`$ and $`$nextLine$`$

The Java $`$String$`$ class include a method named $`$toUpperCase$`$ that may also be useful.
