Spring Boot - REST Controllers

Given the controller method:

@GetMapping("/greet")
public String greet(@RequestParam String name) {
    return "Hello, " + name + "!";
}

What will be the output when accessing /greet?name=Anna?

AHello, Anna!

BHello, null!

CHello, !

DError: Missing required parameter

Step-by-Step Solution

Solution:

Step 1: Understand @RequestParam behavior
The method expects a query parameter 'name' which is required by default.
Step 2: Check the URL query string
The URL provides ?name=Anna, so the method receives "Anna" as the parameter.
Final Answer:
Hello, Anna! -> Option A
Quick Check:
Query param 'name' = Anna, output greeting = D [OK]

Quick Trick: If param is required and given, output uses it directly [OK]
