Spring Boot - Advanced Patterns

Given the following Spring Boot code snippet, what will be the output if the feature flag "betaFeature" is disabled?

if(featureFlagService.isFeatureEnabled("betaFeature")) {
    System.out.println("Beta feature is ON");
} else {
    System.out.println("Beta feature is OFF");
}

ABeta feature is ON

BBeta feature is OFF

CNo output

DRuntime error

Step-by-Step Solution

Solution:

Step 1: Understand the condition check
The code prints "Beta feature is ON" only if the flag is enabled (true).
Step 2: Analyze the flag state given
The flag "betaFeature" is disabled, so isFeatureEnabled returns false, triggering the else block.
Final Answer:
Beta feature is OFF -> Option B
Quick Check:
Flag disabled = else block runs [OK]

Quick Trick: Disabled flag triggers else block output [OK]

Common Mistakes:

Assuming disabled flag prints ON message
Expecting no output when else block exists
Thinking code throws error on false flag
