Изображение
1. Compiler - takes the entire programming code written in high language and translates the whole of it into machine code at once. After this process the an executable file will be ready to run. The translation takes some times to be done, but after that execution is so fast. 2. Interpreter - takes each single instructions of the code translates it and then executes it on its own. The translation step is before the program runs is fast, but execution is slow. JDK = JRE + development tools JRE = JVM + library class JDK -> Java Development Kit. A kit which provides the environment to develop and execute (run) Java program. JRE -> Java Runtime Environment. Provides environment to only run. JVM -> Java Virtual Machine f * Compiled: Fortran, C, C++, Pascal, Haskell, Rust, Go * Interpreted: JavaScript, PHP, Python, Ruby Java both compiled and interpreted language.
