Top 10 Java interview questions

Posted by Stephen thangaraj at 16:24
The 10 most frequently-asked Java interview questions, in my experience.Mostly used in phone interviews to “weed out” the weakest candidates.

These questions are fairly simple so getting them wrong will raise a major red flag.

For the same reason I wont bother printing the answers, unless somebody specifically asks for it in the comments.

In no particular order:

- How to prevent concurrent access to a method
- Meaning of the volatile keyword
- Difference String and StringBuffer
- Difference between ArrayList and Vector
- Relationship between equals and hashcode
- Difference between checked and unchecked exceptions
- Meaning of the final keyword
- Explain garbage collection, can it be forced
- Difference between an interface and a abstract class
- what’s a deadlock
