12 Microservices Best Practices You Need to Know
β Single Responsibility: Keep your services focused on one task to enhance maintainability.
β Containers: Use containers to package applications and dependencies for consistent environments.
β Orchestration: Manage and coordinate multiple services effectively using orchestration tools.
β Resilience and Fault Tolerance: Build robust systems that can handle failures gracefully.
β Scalability: Design your services to scale easily when user demand increases.
β CI/CD: Implement continuous integration and delivery for faster and more reliable software updates.
β Observability: Monitor and analyze system performance to identify and troubleshoot issues.
β Security: Prioritize security measures to protect your services and data.
β API Gateway: Use an API gateway to manage and route traffic to your microservices.
β Stateless: Design services to be stateless for better scalability and efficiency.
β DB Per Service: Isolate data storage by assigning a separate database for each service.
β Event Driven Architecture: Use event-driven approaches for better communication between services.

Java's enhanced switch expressions allow for more compact and readable code.
By using the new arrow syntax (->), this reduces boilerplate (break statements) and organizes the code more clearly.
This approach is less error-prone and easier to read, especially as more cases are added.

Reducing Nesting with Early RETURN
β
Why Senior's Code is Better: Early returns reduce nesting, making the code easier to read and understand. It simplifies the control flow by handling special cases upfront.
β
Real-World Impact: Cleaner code improves maintainability and reduces the chances of bugs introduced by deeply nested conditions.

Learning Java can be hard unless you have a good foundation
Start with these basics:
β Variables
β Data Types
β Methods
β Objects
β Classes
β Loops
β Arrays
β Inheritance
Once you're comfortable, dive deeper into these topics:
β Conditionals (if, switch)
β Interfaces
β Abstract Classes
β Exception Handling
β Collections Framework (List, Set, Map)
β Generics
β Streams and Lambda Expressions
β Multithreading and Concurrency
β File I/O (Input/Output)
β JDBC (Java Database Connectivity)
β Annotations
β Design Patterns (Singleton, Factory, etc.)
β Java Memory Management (Garbage Collection)
β JVM Architecture
Learn the basics first and the advanced topics will be easier!

20 Git Command-Line Tricks Every Developer Should Know
1. git add -p -> Stage parts of a file interactively, allowing selective commits.
2. git reset --soft HEAD~1 -> Undo the last commit, keeping changes in your working directory.
3. git fetch --all --prune -> Fetch all remote changes and remove deleted branches locally.
4. git commit --amend -> Modify the most recent commit, useful for minor changes.
5. git stash -> Save current changes temporarily without committing.
6. git stash pop -> Apply and remove the most recent stash.
7. git cherry-pick <commit-hash> -> Copy a specific commit to the current branch.
8. git branch -d <branch-name> -> Delete a local branch.
9. git log -- <file> -> View the history of a specific file.
10. git blame <filename> -> See who last modified each line in a file.
11. git bisect start -> Start a binary search to find the commit causing a bug.
12. git merge --abort -> Cancel an in-progress merge and revert to the previous state.
13. git log --grep="search term" -> Search commit messages for keywords.
14. git tag -a v1.0 -m "Version 1.0 release" -> Create an annotated tag with metadata.
15. git clean -fd -> Remove untracked files and directories.
16. git reflog -> Show a log of all operations, useful for recovering lost commits.
17. git rebase -i HEAD~<number-of-commits> -> Squash multiple commits into one.
18. git revert <commit-hash> -> Create a new commit that undoes a specific commit.
19. git log --graph --oneline --all -> View a graphical history of all branches.
20. Press TAB for auto-completion -> Speeds up typing and avoids mistakes.

In Java, you should avoid returning null collections. Returning null requires the calling code to perform null checks before iterating, which leads to cluttered code and potential `NullPointerException`s if missed.
Instead of returning null, consider returning:
- new ArrayList<>()
- Collections.emptyList()
- Collections.emptySet()
This approach keeps your code cleaner, ensures safe iteration, and minimizes runtime surprises. Returning empty collections instead of `null` is a best practice for making code safer and more maintainable.
What's your approach to handling empty collections in Java?
