Java code optimization

Hi. I'm looking for a professional java coder to optimize my java code. This program is an information visualization tool that load thousands of XML files on memory and visualize them. This program is made by two grad student as a coursework project and I would like to use this program for some user study experiment. However, I couldn't open large data with this program because of "OutOfMemory error". I'm sure this can be corrected by optimizing some part of the code. You, if selected, will be provided fully working source codes and data, and also provided larger data that cause "outofmemory" problem. Your job is optimize the java code and make it work with larger data. Please see attached requirement document. Thanks. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
