what is difference between Hashmap and concurrent HashMap?

Question

I am new to Stackoverflow searched over google but not able to understand the basic difference between them.

Go through http://ria101.wordpress.com/2011/12/12/concurrenthashmap-avoid-a-common-misuse/. Its a broad and nice article — sanbhat, Jul 28 '13 at 17:54

The ConcurrentHashMap is thread-safe, while the basic HashMap is not. This is explained as well in the official documentation.

Check the possible dup question, there's more on `ConcurrentHashMap` apart from being thread-safe. – Luiggi Mendoza Jul 28 '13 at 17:54
After typing this answer, I saw your link to the dup question. I guess this question will be closed relatively soon ;) – drvdijk Jul 28 '13 at 17:54
