memory problem

[zulqernain]

i am writing a program which is working on a 50MB file i am using hashmaps to store the words in the text file and the count as value and i am using some arrayLIsts having hashmap as values.and now the program gives me error
Exception in thread "main" java.lang.OutOfMemoryError
i tried using the command

java -Xms32m -Xmx128m filename

it speed up the process a bit bit still the error is there

can you please tell me if there is any other command which i can use to get rid of this probelm .i understand it due to makinga lot of objects but now i am finding it hard to chg the structure of my program.

if you think its due to a lot of hashmaps ,if i make a class and make the objects and put in the vector and use that verctor as value of arraylist ..will it be better memory wise?

If you need this amount of memory, you need it! Have you tried increasing the memory available to Java to more than 128M?


-Xmx256m perhaps?
