A JAR ("Java archive") file is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution.[4]
JAR files are archive files that include a Java-specific manifest file. They are built on the ZIP format and typically have a .jar
file extension.[5]
