Not anymore. Last year, [Michael] wrote Java Grinder, a Java byte-code compiler that compiles classes into assembly language instead of being part of a JVM.

Find out how source code is compiled for different programming languages and computer architectures, including the evolution from FORTRAN to CLR and JIT compilers.

Direct execution of Java byte code is possible thanks to a Java extension to the ARM processor core by ARM Ltd., Cambridge, England. Known as Jazelle, the new Java acceleration feature initially ...

The extreme ease with which Java .class files can be reconstructed into Java sources that closely resemble the originals has a lot to do with Java byte-code design goals and trade-offs. Among ...

With a byte code compiler, an assembler, and an API for the Sega-specific hardware, [Mike] set about building his demo. Since this was a Sega, it needed the ‘SEGA’ sound at the start.

The entire game fits in just 1,024 bytes of JavaScript code, less than the size of this post. Developer Marijn Haverbeke used creative coding tricks to reduce the size to a single kilobyte.

With a new extension that ARM is adding to its architecture, you can put the ARM processor core into a state in which it directly executes Java code to allow low-cost and portable platforms to run ...
