Also what is object query language.

Answer 1

Have you read the documentation for JHAT ? It details the various types of queries that can be performed using the heap analysis tool.

最后解决了Eclipse Memory Analyzer，它几乎可以提供从转储中获得的所有内容

Answer 3

You can use the object query language which is a part of JHAT.See which object's are prominent in memory at the time of heap dump and look up in the code if you can reduce unwanted object creation.
