This list of JVM Languages comprises notable computer programming languages that are used to produce computer software that runs on the Java virtual machine JVM. Some of these languages are interpreted by a Java program, and some are compiled to Java bytecode and just-in-time JIT compiled during execution as regular Java programs to improve performance. The JVM was initially designed to support only the language Java. However, over time, ever more languages were adapted or designed to run on the Java platform. ZipPy [13] Graal. Python [9].

Java is a high-level , class-based , object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere WORA , [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. The Java runtime provides dynamic capabilities such as reflection and runtime code modification that are typically not available in traditional compiled languages. Java gained popularity shortly after its release, and has been a very popular programming language since then. Java was originally developed by James Gosling at Sun Microsystems.

The following code in Java SE 7 is equivalent to the code in the previous example:. The use of garbage collection in a language can also affect programming paradigms. Archived PDF from the original on April 5, Retrieved April 22, Original Description:. When no references to an object remain, the Java garbage collector automatically deletes the unreachable object, freeing memory and preventing a memory leak. Methods are similar to functions except they belong to classes. Archived from the original on July 15, Archived from the original on August 13, Relational "less than" and "less than or equal to".

Java is a widely-used programming language for coding web applications. It has been a popular choice among developers for over two decades, with millions of Java applications in use today.

These are: [8] [9] [10]. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The Elements of Java Style. The use of a JIT compiler means that Java applications, after a short delay during loading and once they have "warmed up" by being all or mostly JIT-compiled, tend to run about as fast as native programs. If the superclass does not have a constructor without parameters the subclass must specify in its constructors what constructor of the superclass to use. Main article: JavaFX. J2SE was the designation for the Standard Edition. Next, the layout of the frame is set to a BorderLayout ; this tells Swing how to arrange the components that will be added to the frame. Bill Joy had envisioned a new language combining Mesa and C. Or rather, the lack thereof ". Meanwhile, most modern smartphones, tablet computers , and other handheld PCs that run Java apps are most likely to do so through support of the Android operating system , which includes an open source virtual machine incompatible with the JVM specification. Java's performance has improved substantially since the early versions.
