英文译文:An interpreter is a program that directly executes instructions written in a programming language. Only when the program is executed, it is interpreted into machine language to be executed by the computer one by one, so the running speed is not as fast as the compiled program. Executi...
Java can be considered both a compiled and an interpreted language because its source code is first compiled into a binary byte-code. This byte-code runs on the Java Virtual Machine (JVM), which is usually a software-based interpreter. The use of compiled byte-code allows the interpreter (...
Compiled vs. Interpreted.Java is considered acompiledprogramming language. JavaScript is considered aninterpretedscripting language. The difference is in the implementation: Java is compiled into bytecode and runs on a virtual machine, whereas JavaScript can be interpreted directly by a browser in the ...
例如C、C++；解释型语言（interpreted language）指由解释器（interpreter）直接执行，不需要编译成机器语言...
Interpreted, compiled, and native frames all use the same stack Preemptive multithreading based on native threads Accurate generational and compacting garbage collection Ultra-fast thread synchronization Dynamic deoptimization and aggressive compiler optimizations ...
Java is both a compiled and an interpreted language. Java source code is turned into simple binary instructions, much like ordinary microprocessor machine code. However, whereas C or C++ source is reduced to native instructions for a particular model of processor, Java source is compiled into a ...

_from_compiled_entry:编译器入口。最开始指向c2i适配器入口,在字节码经过编译后会改变地址,指向编译好的代码。 _code:代码入口。当编译器完成编译后会指向编译后的本地代码。 有了上面的知识,方法链接的源码就很容易理解了。如代码清单2-10所示,链接阶段会将i2i_entry和_from_interpreter_entry都指向解释器入口,另...
解释模式(Interpreted Mode):参数"-Xint",编译器完全不介入工作,全部代码都使用解释方式执行 编译模式(Compiled Mode):参数"-Xcomp",优先采用编译方式执行程序,但是解释器仍然要在编译无法进行的情况下介入执行过程 HotSpot虚拟机采用分层(Tiered Compilation)的策略,分层编译根据编译器编译、优化的规模与耗时,划分出不同...
