我想更好地理解其中的区别。我在网上找到了很多解释,但它们都倾向于抽象的差异,而不是实际的含义。

Most of my programming experiences has been with CPython (dynamic, interpreted), and Java (static, compiled). However, I understand that there are other kinds of interpreted and compiled languages. Aside from the fact that executable files can be distributed from programs written in compiled languages, are there any advantages/disadvantages to each type? Oftentimes, I hear people arguing that interpreted languages can be used interactively, but I believe that compiled languages can have interactive implementations as well, correct?

语言本身既不编译也不解释,只有语言的特定实现才是。Java就是一个很好的例子。有一个基于字节码的平台(JVM)、一个本机编译器(gcj)和一个用于Java超集(bsh)的互用器。那么Java现在是什么呢?字节码编译,本机编译还是解释?

其他既编译又解释的语言有Scala、Haskell或Ocaml。每种语言都有一个交互式解释器,以及一个字节码或本机机器码的编译器。

所以一般来说,用“编译型”和“解释型”来划分语言并没有多大意义。

其他回答

The Python Book©2015 Imagine Publishing Ltd,简单地通过第10页中提到的以下提示来区分差异:

像Python这样的解释型语言是指将源代码转换为机器码,然后在每次程序运行时执行的语言。这与编译语言(如C)不同,后者只将源代码转换为机器代码一次——然后在程序每次运行时执行生成的机器代码。

很难给出一个实际的答案,因为差异在于语言定义本身。可以为每一种编译语言构建一个解释器,但不可能为每一种解释语言构建一个编译器。它主要是关于语言的正式定义。所以在大学里没有人喜欢理论信息学。

Compile is the process of creating an executable program from code written in a compiled programming language. Compiling allows the computer to run and understand the program without the need of the programming software used to create it. When a program is compiled it is often compiled for a specific platform (e.g. IBM platform) that works with IBM compatible computers, but not other platforms (e.g. Apple platform). The first compiler was developed by Grace Hopper while working on the Harvard Mark I computer. Today, most high-level languages will include their own compiler or have toolkits available that can be used to compile the program. A good example of a compiler used with Java is Eclipse and an example of a compiler used with C and C++ is the gcc command. Depending on how big the program is it should take a few seconds or minutes to compile and if no errors are encountered while being compiled an executable file is created.check this information

简短的(不精确的)定义:

编译语言:将整个程序立即转换为机器代码,然后由CPU运行机器代码。

解释语言:逐行读取程序,一旦读取一行,CPU就会执行该行的机器指令。

但实际上,现在很少有语言是纯编译或纯解释的,它们通常是混合的。想要更详细的图片描述,请看这个帖子:
