Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .
In computing, the Java Cryptography Architecture (JCA) is a framework for working with cryptography using the Java programming language. It forms part of the Java security API, and was first introduced in JDK 1.1 in the java.security package. The JCA uses a "provider"-based architecture and contains a set of APIs for various purposes, such as ...
The Java Cryptography Extension (JCE) is an officially released Standard Extension to the Java Platform and part of Java Cryptography Architecture (JCA). JCE provides a framework and implementation for encryption , key generation and key agreement , and Message Authentication Code (MAC) algorithms.
IAIK-JCE is a Java-based Cryptographic Service Provider, which is being developed at the Institute for Applied Information Processing and Communications (IAIK) at the Graz University of Technology. It offers support for many commonly used cryptographic algorithms, such as hash functions , message authentication codes , symmetric , asymmetric ...
A compiler may use one large symbol table for all symbols or use separated, or hierarchical symbol tables for different scopes. For example, in a scoped language such as Algol or PL/I a symbol "p" can be declared separately in several procedures, perhaps with different attributes. The scope of each declaration is the section of the program in ...
In Java, the signature of a method or a class contains its name and the types of its method arguments and return value, where applicable. The format of signatures is documented, as the language, compiler, and .class file format were all designed together (and had object-orientation and universal interoperability in mind from the start).

Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...
