Hi:
I just have one mission to read a huge file(more than 500M) using
java. Is there anyone having such kind of experiences on that?
My system is Java1.1.7a and running on Windows95/NT or Linux with
X-windows. And my runtime configuration is setting up 100M to 500M
memory size ,but my real Hdisk just left 500M free space.
In my program, Firstly, I used the DataInputStream to read one byte by
byte, but it seems too slow.
Then I used the ReadFully to read the whole file into one large btye
array. The performance imporved a lot.
But what I will deal with is the huge file, more than 500M, how can I
allocate this huge array?
Does anyone have such experience on that?
Is there any way to free the array I allocated like in C/C++? It seems
the only way to free the unused memory is done by garbage collection
thread, do I have any way to destory the memory which I allocated just
using one method ???
Any hint will be appreciated !!!
Best Regard
Kevin Zhu
