Java Archives (JARs) wrap a Java application into a single archive file for deployment, distribution, and execution. Use this course to acquaint yourself with building Java archives or JAR files using the JAR utility, run from the command line.
Over the length of the course, you'll outline how a simple Java project packaged into a JAR file can be executed directly, different attributes of a JAR manifest can affect the use of a JAR file, and a project with external dependencies can be packaged into an executable JAR.
Upon completion of this course, you'll be able to build different Java archives: JAR with multiple main classes, JAR containing several packages, and JAR that is not directly executable by itself but usable as a dependency in other projects.
