Write once, run anywhere ( WORA ), or sometimes Write once, run everywhere ( WORE ), was a 1995 [1] slogan created by Sun Microsystems to illustrate the cross-platform benefits of the Java language. [2] [3] Ideally, this meant that a Java program could be developed on any device, compiled into standard bytecode, and be expected to run on any ...
This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language . Note that any referenced "value" refers to a 32-bit int as per the ...
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 ...

Java bytecode is used at runtime either interpreted by a JVM or compiled to machine code via just-in-time (JIT) compilation and run as a native application. As Java bytecode is designed for a cross-platform compatibility and security, a Java bytecode application tends to run consistently across various hardware and software configurations.
List of Java APIs. There are two types of Java programming language application programming interfaces (APIs) : The official core Java API, contained in the Android (Google), SE (OpenJDK and Oracle), MicroEJ. These packages (java.* packages) are the core Java language packages, meaning that programmers using the Java language had to use them in ...
An interface in the Java programming language is an abstract type that is used to declare a behavior that classes must implement. They are similar to protocols. Interfaces are declared using the interface keyword, and may only contain method signature and constant declarations (variable declarations that are declared to be both static and final ...
Java concurrency. The Java programming language and the Java virtual machine (JVM) is designed to support concurrent programming. All execution takes place in the context of threads. Objects and resources can be accessed by many separate threads. Each thread has its own path of execution, but can potentially access any object in the program.
