Performance Abstract classes vs. Interfaces, Lambda and DB Connections, JMH--Questions for 127th airhacks.tv 📎
- performance: abstract class vs. interface
Hi, I got an interview question as to which one is faster Abstract class or Interface ? Can you explain please.
What is Faster: String.join or Collectors.joining? - DB connections and lambda shutdown
- performance measurement with or without JMH:
"PLEASE use the microbenchmark harness in future videos. I have the impression, that this suggests that performance measurements with after-minus-before is a good idea."
