Call One Method from Another

In this problem, read one line from standard input as a name, implement createGreeting(String name) to build and return a greeting string, and showGreeting(String name) to call it and print the result. In the main method, use Scanner to read the name and call showGreeting(name).

Input: A string representing a name (one line)
Output: One line in the format Hello, {name}!

Learning Objectives:

• Apply the procedural decomposition pattern of calling one method from another
• Understand the separation of roles between a value-returning method and a display method
• Improve code reusability and readability by splitting logic into small methods
