Typical interview question is "Can you explain the difference between final, finally, and finalize in Java?". And it is pretty straightforward:

I have recently troubleshooted Java code and stumbled upon an interesting issue. Basically what it came down to was what is the difference between '==' and '.equals()' in Java.
Can you please briefly elaborate when would you use one over the other?
I'm aware of some of the ORACLE JDK profiling tools, many of them command-line based. Do you know if those tools are available for every JDK implementation or only available for specific implementations like ORACLE JDK or Open JDK Hotspot?
Thanks in advance for your attention and your answers.
