A Java compiler is a compiler for the Java programming language.
Some Java compilers output optimized machine code for a particular hardware/operating system combination, called a domain specific computer system. An example would be the now discontinued GNU Compiler for Java.[1]
The most common form of output from a Java compiler is Java class files containing cross-platform intermediate representation (IR), called Java bytecode.[2]
The Java virtual machine (JVM) loads the class files and either interprets the bytecode or just-in-time compiles it to machine code and then possibly optimizes it using dynamic compilation.
A standard on how to interact with Java compilers was specified in JSR 199.[3]
It is provided by module jdk.compiler, and requires the full Java Development Kit (as opposed to just the Java Runtime Environment), and reside in the javax.tools.* namespace.[4]

}

System.out.printf("Compilation result: %s%n", result == 0 ? "Success" : "Failure");

A Java compiler is a compiler for the Java programming language. Some Java compilers output optimized machine code for a particular hardware/operating system combination, called a domain specific computer system. An example would be the now discontinued GNU Compiler for Java. The most common form of output from a Java compiler is Java class files containing cross-platform intermediate representation (IR), called Java bytecode.

It is provided by module jdk.compiler, and requires the full Java Development Kit (as opposed to just the Java Runtime Environment), and reside in the javax.tools.* namespace.
The GNU Compiler for Java (GCJ) is a discontinued free compiler for the Java programming language. It was part of the GNU Compiler Collection. GCJ compiles Java source code to Java virtual machine (JVM) bytecode or to machine code for a number of CPU architectures. It could also compile class files and whole JARs that contain bytecode into machine code.
In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code, like an attribute. Classes, methods, variables, parameters and Java packages may be annotated. Like Javadoc tags, Java annotations can be read from source files. Unlike Javadoc tags, Java annotations can also be embedded in and read from Java class files generated by the Java compiler. This allows annotations to be retained by the Java virtual machine at run-time and read via reflection. It is possible to create meta-annotations out of the existing ones in Java.
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages, referred to as JVM languages, that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform. The JVM reference implementation is developed by the OpenJDK project as open source code and includes a JIT compiler called HotSpot. The commercially supported Java releases available from Oracle are based on the OpenJDK runtime. Eclipse OpenJ9 is another open source JVM for OpenJDK.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
