Java analyze performance

How do I analyze and conclude the performance of simple java program in general like have i used the right datatypes, do the program executes in less time, would i suppose to use any other datatypes for better performance etc. Kindly let me know your suggestions. I mainly just log the raw performance statistics to a daily rolling file. Then i use the jar on the command line to analyse the data with different timeslices as i please. I often use the -g commandline option to output a html file which i can then open up and view the data visually which is really useful.

JProfiler an extremely good Java profiler combining CPU, memory and thread profiling into one application and is useful for developers as it can be used to analyze performance bottlenecks, memory leaks, CPU loads, resolve threading issues. It supports local profiling (analysis of applications that are running on the same machine on which the JProfiler software is installed) and remote profiling (this is where it allows for the analysis of Java applications which are running on remote The performance of a Java bytecode compiled Java program depends on how optimally its given tasks are managed by the host Java virtual machine (JVM), and how well the JVM exploits the features of the computer hardware and operating system (OS) in doing so. Thus, any Java performance test or comparison has to always report the version, vendor, OS and hardware architecture of the used JVM. Use a profiler to see where your application spends its time.
