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 (), meaning that compiled Java code can run on all platforms that support Java without the need to recompile.
Java syntax. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike in C++, in Java there are no global functions or variables, but there are data members which are also regarded as global variables. All code belongs to classes and all values are objects.

Write once, run anywhere. 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 ...
List of Java keywords. A snippet of Java code with keywords highlighted in blue and bold font. In the Java programming language, a keyword is any one of 68 reserved words [1] that have a predefined meaning in the language. Because of this, programmers cannot use keywords in some contexts, such as names for variables, methods, classes, or as any ...
Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices, and methods for each aspect of a program written in that language.
