Java code is the best example of compiled as well as interpreted. Java Compiler does the task of compiling . Java file to .class file(binary form). JVM works as interpreter to let Operating system understand the compiled code instructions.

compiler compiles the high level language code into binary code and it will be done in one shot. Whereas interpreter will also do the same but line by line

The interpreter takes one statement then translates it and executes it and then takes another statement. While the compiler translates the entire program in one go and then executes it. - Compiler generates the error report after the translation of the entire page while an interpreter will stop the translation after it gets the first error. - Compiler takes a larger amount of time in analyzing and processing the high level language code comparatively interpreter takes lesser time in the same process. - Besides the processing and analyzing time the overall execution time of a code is faster for compiler relative to the interpreter. read less

Programming Languages which generate binary file will use the compiler. Programming Languages which is not generating binary file will use the interpreter. Which is also called as scripting languages. Binary file will be running very fast when compare to script. In Binary file, the processor fetch the binary contents directly and running without any further conversion. In case of script, the process will fetch each instruction at a time and converted into binary and execute. Hence it requires more time when compare to binary. Binary file will consume less memory/resource when compare to script. Binary will not be generated unless are syntax errors are rectified. Script will be exectuted, and stop when error occurred. Once error is rectified again continue execution from that line. Example C, C++ are programming languages which are used compiler to convert into binary format PHP, PERL are programming languages which are used interpreter to convert each instruction at a time, convert into binary then go to next instruction. read less

Compiler A compiler is defined as a computer program that is used to convert high level instructions or language into a form that can be understood by the computer. Since computer can understand only in binary numbers so a compiler is used to fill the gap otherwise it would have been difficult for a human to find info in the 0 and 1 form. Earlier the compilers were simple programs which were used to convert symbols into bits. The programs were also very simple and they contained a series of steps translated by hand into the data. However, this was a very time consuming process. So, some parts were programmed or automated. This formed the first compiler. More sophisticated compliers are created using the simpler ones. With every new version, more rules added to it and a more natural language environment is created for the human programmer. The complier programs are evolving in this way which improves their ease of use. There are specific compliers for certain specific languages or tasks. Compliers can be multiple or multistage pass. The first pass can convert the high level language into a language that is closer to computer language. Then the further passes can convert it into final stage for the purpose of execution. Interpreter The programs created in high level languages can be executed by using two different ways. The first one is the use of compiler and the other method is to use an interpreter. High level instruction or language is converted into intermediate from by an interpreter. The advantage of using an interpreter is that the high level instruction does not goes through compilation stage which can be a time consuming method. So, by using an interpreter, the high level program is executed directly. That is the reason why some programmers use interpreters while making small sections as this saves time. Almost all high level programming languages have compilers and interpreters. But some languages like LISP and BASIC are designed in such a way that the programs made using them are executed by an interpreter. Difference between compiler and interpreter • A complier converts the high level instruction into machine language while an interpreter converts the high level instruction into an intermediate form. • Before execution, entire program is executed by the compiler whereas after translating the first line, an interpreter then executes it and so on. • List of errors is created by the compiler after the compilation process while an interpreter stops translating after the first error. • An independent executable file is created by the compiler whereas interpreter is required by an interpreted program each time. read less
