About JAR (.JAR)
JAR stands for Java ARchive, a file format used to package multiple Java class files and associated metadata into a single file. It is commonly used to distribute Java applications and libraries in a compressed format, making deployment simpler and more efficient.
Technical Details
Technically, a JAR file is built on the ZIP file format and uses the .jar extension. It supports compression and archiving of Java bytecode, resources, and metadata, and can be executed by the Java Runtime Environment (JRE) if it contains a manifest specifying the main class.
Additional Information & Use Cases
JAR files can include an optional manifest file that specifies entry points and other configuration data, enabling the JAR to be executable. The format was introduced by Sun Microsystems with the release of the Java Development Kit (JDK) 1.2 in 1998, helping standardize Java application packaging.
