Now im learning Java on which topics i must have a grip to get job in MNC's

Question

Beginner

Answer 1

The OOP concepts have the most weightage and you are likely to get almost all of your questions from this topic.

Apart from that learn Strings, Arrays, exception handling and a little understanding of multi-threading would be enough I guess for an entry level job.

Edit: Collections is must and also try to learn file handling concepts.
