Is Coffee Compiled Or Interpreted Programming Language?
One of the outset inquiry a graduate C or C++ programmer, who has simply started learning Java inquire is, whether Java is a compiled linguistic communication or an interpreted one? On academic courses or during college, students larn a lot of languages e.g. VB, C, C++ as well as they happily categories them equally either compiled or interpreted, but amongst Java it's tricky. It's non clear whether Java is compiled or interpreted, because it neither generate machine linguistic communication code later compiling root file, neither interpreted root file to execute teaching trouble past times line. In guild to respond this inquiry y'all ask to fist know that Java is a platform independent language? Which way y'all tin hand notice run a Java programme to whatsoever platform, which includes hardware + operating system, without whatsoever modification. Knowing how Java achieves platform independence is key to respond this question.
If anyone inquire this inquiry during interview, therefore your respond should last both i.e. Java is both compiled as well as interpreted programming language. Java code is written inward .java files (also known equally root file), which is compiled past times javac, a Java compiler into shape files.
Unlike C or C++ compiler, Java compiler doesn't generate native code. These shape files contains byte-code, which is dissimilar than machine or native code. Java virtual machine or JVM interprets byte codes during execution of Java program.
So, y'all tin hand notice run across it's both compiled as well as interpreted language, but this respond is incomplete until y'all scream close JIT (Just inward fourth dimension compiler) which does or therefore other circular of compilation to arrive at native code, which tin hand notice straight last executed past times corresponding platform.
We volition larn close how JIT works inward side past times side section.
When JVM interprets Java byte code, it too gathers useful statistics, similar which business office of code is hot as well as ever run. Once JVM has plenty information to brand such decision, JIT tin hand notice compile that business office of code e.g. method or block into native code.
This native code volition therefore straight last executed past times machine, without interpreting past times JVM. JIT provides immense functioning boost to Java application as well as this is i to a greater extent than argue why Java is too used to write high functioning application similar electronic trading systems, algorithmic gateways etc, along amongst native languages similar C as well as C++.
In short, Java is both compiled as well as interpreted language. It compiles using javac and JIT, as well as interprets using Java virtual machine. Here is the sequence of things usually happens from writing to execution of a Java programme :
1) Programmer write root code as well as shop that into a .java file. Always retrieve scream of your Java root file must last same amongst the populace shape declared within that file, for example if in that location is populace shape called Order within Java file, therefore it scream must last Order.java.
2) javac compiles .java fie as well as creates class files, which contains byte code. This byte code is principal argue of Java beingness platform independent.
3) JVM executes these shape files as well as gathers statistics of execution run. These statics are used to create upwardly one's heed hot location i.e. business office of your code which executes 90% of time.
4) After certainly threshold, when JVM has plenty information to brand decision, JIT compiles often used byte codes into native code, which is therefore straight executed past times platform. This provides functioning boost to Java application.
That's all folks, You tin hand notice straightaway tell that Java is both compiled as well as interpreted language. Some people fifty-fifty called Java equally dynamically compiled language, referring to compiling byte code into native code during runtime. While answering this inquiry during interview, ever retrieve to scream close JIT compilation equally converting Java root code to shape files is non genuinely compilation inward truthful C as well as C++ programming sense, where compiler arrive at native code.

Java is both Compiled as well as Interpreted Language but how?
Above respond is absolutely right but its non complete. What javac (Java compiler, which comes along JDK) does is pseudo compilation, it doesn't convert Java root code into native code, which tin hand notice straight last executed past times CPU, existent compilation into native code is done past times or therefore other programme called Just inward Time compiler, too known equally JIT. This is genuinely an optimization done on JVM past times Java platform engineers.When JVM interprets Java byte code, it too gathers useful statistics, similar which business office of code is hot as well as ever run. Once JVM has plenty information to brand such decision, JIT tin hand notice compile that business office of code e.g. method or block into native code.
