Can GCC compile Java?
GCJ can compile Java source files to native code or to Java bytecode and can also compile Java bytecode to native code.
Why Java is a platform?
Like the C compiler, the Java compiler does not produce native executable code for a particular machine. Instead, Java produces a unique format called bytecode. It executes according to the rules laid out in the virtual machine specification. Therefore, Java is a platform-independent language.
Can MinGW compile Java?
Support for Windows using MinGW is also available. It can compile Java source code to either Java bytecode (class files) or native machine code. It can also compile Java bytecode to native machine code. GCJ native code can be executables or shared libraries.
Is Linux a GNU?
Whether you use GNU/Linux or not, please don’t confuse the public by using the name “Linux” ambiguously. Linux is the kernel, one of the essential major components of the system. The system as a whole is basically the GNU system, with Linux added. When you’re talking about this combination, please call it “GNU/Linux.”
Does Ubuntu use GNU?
Ubuntu was created by people that had been involved with Debian and Ubuntu is officially proud of its Debian roots. It’s all ultimately GNU/Linux but Ubuntu is a flavor. In the same way that you can have different dialects of English. The source is open so anyone can create their own version of it.

What is Javac command?
Description. The javac command reads source files that contain module, package and type declarations written in the Java programming language, and compiles them into class files that run on the Java Virtual Machine. The javac command can also process annotations in Java source files and classes.
Is Java an OS?
JavaOS is an operating system based on a Java virtual machine and predominantly used on SIM cards to run applications on behalf of operators and security services. It was originally developed by Sun Microsystems.
Why Java is not pure object-oriented?
Java is not fully object oriented because it supports primitive data type like it,byte,long etc.,which are not objects. Because in JAVA we use data types like int, float, double etc which are not object oriented, and of course is what opposite of OOP is. That is why JAVA is not 100% objected oriented.
Is Java a hardware?
The Java platform differs from most other platforms in that it’s a software-only platform that runs on top of other, hardware-based platforms. Most other platforms are described as a combination of hardware and operating system. The Java platform has two components: The Java Virtual Machine (Java VM)
What is Graalvm native image?
Native Image is a technology to ahead-of-time compile Java code to a standalone executable, called a native image. This executable includes the application classes, classes from its dependencies, runtime library classes, and statically linked native code from JDK.
