Improve Memory Efficiency and Data Structure Usage for Java

[imz87]

This PR addresses memory optimization and performance issues in the existing Java sample code. The following changes have been made to improve the code:

Optimized Lambda Expressions:

Replaced lambdas that unnecessarily create new class instances in each iteration, reducing memory overhead.

Refactored Duration.ofSeconds(10) Usage:

Updated the implementation to minimize its negative performance impact.

Improved Data Structure Selection:

Replaced ArrayList with LinkedList where it was more appropriate for the use case, ensuring better alignment with the required operations.

These changes aim to enhance memory efficiency and overall performance without altering the intended functionality of the original code.

Let me know if any further adjustments are needed.

Best regards,
