![]() ![]() ![]() Some examples of compiled languages include C, C++, and Fortran. The resulting machine code is specific to the hardware architecture and operating system for which it was compiled, making it less portable than interpreted code. The process of compiling a program usually involves several steps, including lexical analysis, parsing, semantic analysis, code optimization, and code generation. This makes them generally faster than interpreted languages, because the machine does not need to perform interpretation at runtime. Compiled LanguagesĬompiled languages are transformed into machine code, which is directly executable by the machine. Instead, the bytecode is interpreted by the JVM at runtime. Java is often described as a compiled language because it uses a bytecode format, which is compiled from source code, but is not directly executable by the machine. Compiled languages are transformed into machine code before execution, while interpreted languages are executed directly by an interpreter. There are two main approaches to executing code: compilation and interpretation. Moreover, if a block of code is executed multiple times, it’ll be interpreted multiple times, which is why interpretation is typically slower than executing a pre-translated machine language program. However, if a command can’t be executed according to the logic of the program, it won’t be translated. For program execution, the interpreter takes one high-level program command, determines the necessary machine operations for its execution, and performs them. Alternatively, you can use a process called interpretation, which involves using an interpreter to translate and execute the program command-by-command, as needed.Īn interpreter is a program that works similarly to a processor in a “take command and execute” cycle. If you want your program to run on a computer with a different type of processor, you need to re-compile it using a different compiler that can generate the appropriate machine language. The compiler takes in a high-level program and translates it into a machine-executable program, which can be executed multiple times. They need to be translated into machine language first, using a special type of computer program called a compiler. However, programs written in high-level languages can’t be executed directly on a computer. Some examples of high-level languages include Java, C, C++, C#, and Pascal. That’s why almost all programs are written in high-level languages, which are designed to be easily understood by humans. Although it’s technically possible to write a program using machine language, it’s impractical and prone to errors, even for the simplest programs.
