Is following scenario called memory-leak in java? Is it not Garbage Collected? -

-

If an object variable is still pointing to some object which is of no use, then JVM The garbage will not collect the object and the object will be in memory to create memory leakage.

There is a possibility of memory leak in the above scenario. Why is not this garbage collection? Can anyone be expanded about this?

As long as someone refers to an object, JVM can not assemble it.

JVM determines that groups of objects are still used in search of an object of queries in the way of context from the root. This means that a group of objects that refers to each other, but is not referred to the rest of the system, the garbage will be collected.

So just pointing to an object will not prevent you from collecting garbage.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
