Java Performance Boost: Optimize Your Code Like a Pro

Want to boost your Java performance like a pro? Here’s how:
1. Use StringBuilder over + for string concatenation in loops — way faster.
2. Avoid unnecessary object creation — reuse where you can.
3. Profile your code — guesswork is slower than VisualVM or JFR.
4. Use parallel streams wisely — they’re powerful, but only when used right.
5. Cache expensive operations — think database calls or file reads.
Fast Java code isn’t magic — it’s smart decisions, line by line.
