Java is one of the most popular programming languages in the world, and for good reason. Its versatility and robust ecosystem make it the go-to choice for building everything from enterprise applications to Android apps. But how can you stand out as a Java developer? In this article, I’ll share 10 tricks and techniques that can take your Java skills to the next level and wow your peers.

1. Use Streams Like a Pro

Streams can make your code concise and expressive. For instance, here’s how you can transform a list of strings into uppercase in one line:

List<String> names = List.of("Alice", "Bob", "Charlie");
List<String> upperNames = names.stream()
                                .map(String::toUpperCase)
                                .toList();

Mastering streams will make your code cleaner and easier to maintain.
