Optimize with a SATA RAID Storage Solution
Range of capacities as low as $1250 per TB. Ideal if you currently rely on servers/disks/JBODs
If I know the operating system on which my program will run, can I compile my Java code into native machine code and run it without the VM?
Yes, it is possible to compile Java code into native code. To do so, you will need a native compiler. VisualAge for Java and Visual Café ship with high-performance native compilers. Unfortunately, the JDK does not ship with native compilers, and I am not familiar with any that are freely available. There are some freely available Java-to-C compilers, however.
URLs for various native compilers and C translators can be found in the Resources section below.
Be warned, though: you may lose certain features of the Java platform if you compile to native code. Further, some of the
older compilers will not allow the dynamic addition of new classes at runtime. When choosing a compiler, carefully compare
the compiler's feature list against your software's requirements, as expected JVM behaviors and features may not carry over
to the compiled code. Native compilers can also be expensive. If you are concerned about performance, adaptive compiling technologies
such as HotSpot and JIT have improved Java performance greatly. Happily, they keep getting better. If your intention is to
simplify the user experience by not requiring the user to type
java <class name> at the command line, you can simply create a
.bat file for Windows or a shell script for Unix that takes care of setting CLASSPATHs and running the program. A batch file could
be as simple as:
run_that_program.bat java program_class_name
