Aug 25, 2009 · Java is a compiled programming language, but rather than compile straight to executable machine code, it compiles to an intermediate binary form called JVM byte code. The byte code is then compiled and/or interpreted to run the program.

Programming languages are classified based on their levels of abstraction. We differentiate high-level languages (Java, Python, JavaScript, C++, Go), low-level (Assembler), and finally, machine code. Every high-level language code, like Java, needs to be translated to machine native code for execution.This translation process can be either compilat...
Let’s start by looking into some basic differences between compiled and interpreted programming languages.
Java and the JVMwere designed with portability in mind. Therefore, most popular platforms today can run Java code. This might sound like a hint that Java is a purely interpreted language. However, before execution, Java source code needs to be compiled into bytecode. Bytecode is a special machine language native to the JVM. The JVM interprets and e...
The javac command-line tool compiles Java source code into Java class filescontaining platform-neutral bytecode: $ javac HelloWorld.java Source code files have .java suffixes, while the class files containing bytecode get generated with .classsuffixes.
The compiled class files (bytecode) can be executed by the Java Virtual Machine (JVM): $ java HelloWorld Hello Java! Let’s now take a deeper look into the JVM architecture. Our goal is to determine how bytecode gets converted to machine native code at runtime.
Technically, it’s possible to compile any static programming language code to machine code directly. It’s also possible to interpret any programming code step-by-step. Similar to many other modern programming languages, Java uses a combination of a compiler and interpreter. The goal is to make use of the best of both worlds, enabling high performan...
In this article, we looked into Java and the JVM internals. Our goal was to determine if Java is a compiled or interpreted language. We explored the Java compiler and the JVM execution engine internals. Based on that, we concluded thatJava uses a combination of both approaches. The source code we write in Java is first compiled into bytecode during...
Feb 2, 2023 · Java is both a compiled and interpreted programming language. Because it employs both compilation and interpretation to run code, it is known as a “compiler-interpreter language.” In order for the Java Virtual Machine to understand the Java code, it must first be compiled into an intermediate format called bytecode (JVM).
So the answer to this question is Java is both Interpreted and compiled. However, it isn't clear whether Java is compiled or interpreted. It neither generates machine code after compiling a source file nor interpreted the source file to execute code instructions line by line.
Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them.
A common question for Java beginners is whether Java is a compiled or interpreted language. The answer is both. Java uses a combination of compilation and interpretation to run programs. This process allows Java to work on different operating systems efficiently.

What is the difference between compiled language and interpreted language?
Java is both a compiled language as well as an interpreted language. The Java code is written in files with the extension .java. This source file is compiled by javac, i.e. the Java compiler into a class file. However, unlike C or C++, the Java compiler generates bytecode instead of native machine code.
