Jul 1, 2001 ... This article gives you an understanding of Java bytecode that will enable you to
be a better programmer. Like a C or C++ compiler translates source code into
assembler code, Java compilers translate Java source code into bytecode. Java
programmers should take the time to understand what the bytecode ...
Apr 14, 2004 ... The Apache Byte Code Engineering Library (BCEL) lets you dig into the
bytecode of Java classes. You can use it to transform existing class
representations or construct new ones, and because BCEL works at the level of
individual JVM instructions, it gives you the utmost power over your code. That
This forum accompanies <a href="http://www.ibm.com/developerworks/views/java
</a>, a monthly column by consultant Dennis Sosnoski covering all things Java
bytecode-related. Here you can comment or raise questions about the material ...
Hi All, I would like to learn about Java Bytecode just to get an idea how a
particular instruction gets executed, can you guys please guide me through any
recommended resource for quick reference ? Thanks Javin Why String is
immutable in Java Java HashMap Tutorial java synchronized keyword example.
Nov 28, 2006 ... I'm exploring various ways to create an extremely non-performance-impacting
profiler. I am currently trying to figure out the right balance between information
and performance when it comes to memory profiling. But when trying out different
things using bytecode, as seen in ...
Nov 9, 2010 ... In these situations, it is helpful to know that when the Java compiler converts your
source code to byte code, it handles synchronized methods and synchronized
blocks very differently. When the JVM executes a synchronized method, the
executing thread identifies that the method's method_info structure ...
As to the other questions: (1) AFAIK labels are only used to define the range of
bytecode instructions for which your local variable is active. That's not just debug
information, though - it's information the JVM needs. You can be sloppy and just
define the variable as active throughout a greater range than you ...
Oct 4, 2005 ... JiBX 1.0 uses classworking techniques to enhance the bytecode for compiled
classes and directly generate new classes. Bytecode generation has some major
advantages over working at the source code level, but it can sometimes get in the
way of building and debugging your application. Even aside ...
I am writing a compiler in Java. I would like to output Java bytecode as the final
output of the compiler. I've been trying to use ASM to accomplish this, however, I
havent quite figured out how to accomplish this. My compiler parses a subset of
Java called Minijava, and generates an AST. I then perform the ...
Dec 18, 2011 ... Further, there are languages that are interpreted by java code - and hence also
run in the JVM. My expectation is this would be slower than those that create
Python via Jython, and Ruby via JRuby (which I personally haven't ...
