Hi [@abhishektripathi66],

I came across the issue regarding the HashMap example and its working, and I’m interested in working on it. I have a good understanding of Java Collections Framework, and I am confident in my ability to implement this efficiently.

Here’s a brief overview of my approach:

1. Creating a HashMap: I will create an instance of HashMap to store key-value pairs.
2. Adding Key-Value Pairs: I will use the put method to add key-value pairs to the HashMap.
3. Retrieving a Value: I will use the get method to retrieve a value by its key.
4. Removing a Key-Value Pair: I will use the remove method to remove a key-value pair from the HashMap.
5. Iterating Over the HashMap: I will use a for loop and the keySet method to iterate over the HashMap.
6. Checking for Keys and Values: I will use the containsKey and containsValue methods to check if the HashMap contains specific keys or values.

Please let me know if I can be assigned this issue. I’m excited to contribute!

Thank you!

Best regards,
Saurabh Singh
