Java Platform: High level language -> Byte code Byte code is executed by VM such as JVM .Net platform: High level language -> CIL (Common Intermediate Language) ---Just in time compiled (JIT)---> Native machine code

2021年5月10日 · Byte code you can say is compiled code and its platform independent thus can run anywhere if it would be machine code which is different for each platform,this is the reason we take intermediate steps to convert convert the compiled code into the machine code at runtime

2013年7月14日 · Each of bytes 68, 73, 9D, 00, 01 is machine code. machine codes are for real machines (CPUs) but byte codes are pseudo machine codes for virtual machines. When you write a java code. java compiler compiles your code and generates byte codes. (A .class file) and you can execute the same code at any platform without changing.

1) What tools are available to view java byte code (preferably available from the linux command line ) The javap tool (with the -c option) will disassemble a bytecode file. It runs from the command line, and is supplied as part of the Java SDK. 2) What are good references to get familiar with java byte code syntax

2010年2月4日 · The Java Compiler compiles Java Source code to class files. The class's methods are translated to Byte Code and the Java virtual machine (JVM) interpretes this byte code. A Just In Time compiler (JIT) may be used to translate the byte code to machine code to speed up execution of class methods.

2015年10月8日 · Of course a byte code can also have an assembly code — meaning a human readable form of it, because "Assembly language" does not necessary mean that it is for a real machine — but it is a human readable form of some native language — for processors, this native language is the machine code — but you also can have assembly code of a ...

2013年5月30日 · So when considering byte code vs native, consider which trade-offs you want to make between portability, security, size, and execution speed. If speed is the only important factor, go native. If any of the others are more important, go with bytecode.

2017年8月22日 · Intellij gives a such warning when compiled code doesn't match the source code, i.e. you try to debug the code but it has changed and not rebuilt. Make sure after you imported your code you didn't modify it. If you modify then first build/compile it before starting the debugger. For example below code will cause this warning :-

2008年10月19日 · There are other language differences but most of them are not expressed at the byte code level, for example, if memory serves, Java's non-static inner classes (which do not exist in .NET) are not a bytecode feature, the compiler generates an additional argument to the inner class's constructor and passes the outer object. The same is true for ...

2013年10月24日 · Note the 2 on the first line; that's the line number in the original source that contains the Python code that was used for these instructions. Python code objects have co_lnotab and co_firstlineno attributes that let you map bytecodes back to line numbers in the original source. dis does this for you when displaying a disassembly.
