Welcome back to QA_AI_WIZARDS.
Today's focus: Unraveling the magic behind finding the first non-repeated character in a string.
This isn't just a tutorial; it's an opportunity to sharpen your Java skills.
Code Explanation:
Core of our code: Java class - FirstNonRepeated.
Armed with a powerful tool: HashMap.

Demonstration:
Applying theory to action with the example string "aabbccde."
Witness the Java masterpiece skillfully pinpointing the first non-repeated character.
Like a skilled detective solving a mystery in the world of code.
Demonstration solidifies explored concepts, showcasing the contribution of each code line.
Prepare to be amazed as the power of HashMaps unfolds in action.
Conclusion:
Successful crafting of a Java masterpiece unveiling the first non-repeated character.
Trusting this tutorial solved the mystery and enriched your understanding of HashMaps and string manipulation in Java.
