Challenge: String Manipulation
In this challenge, you will practice manipulating strings by extracting and transforming specific parts of a Java String. This exercise will help you reinforce your understanding of reference types and common string operations, which are essential skills when working with user input or formatting output.
Suppose you are given a person's full name in the format First Last (for example, John Doe). Your task is to extract the first letter of each name part, convert them to uppercase, and print them together as the person's initials. If the input is John Doe, the output should be JD. You will use string methods such as split, charAt, and toUpperCase to accomplish this.

Write a method that extracts the initials from a full name string and returns them as an uppercase string. The main method should call this method and print the returned initials using the template: "Initials: AB" where "AB" are the initials.
- Implement a method that takes a
Stringparameter representing the full name and returns a string containing the initials in uppercase. - In the main method, call this method with the
fullNamevariable and print the initials using the template:"Initials: AB"where "AB" are the initials.

Can you show me an example input and expected output?
What should I do if the input has more than two names?
Can you explain how to use the split and charAt methods in this context?
Awesome!
