Optimizing<\/strong><\/h4>\n

J2ME applications usually do not run like native C++ applications. The performance is always penalized in terms of speed and memory footprint (RAM). For performance tuning of any J2ME application certain factors can be considered while writing programs(coding) like I\/O, threading etc. This article contains tips discussing how to improve performance of a J2ME application by considering many such factors.<\/p>\n
