The Java Archive Tool is a command-line utility and here are the commands associated with the different capabilities: You can also view, extract, run, and create JAR files with the Java Archive Tool provided as part of the Java Development Kit (JDK) included in the Oracle Java SE Development Kit. When you do this on a Mac, Apple Jar Launcher (bundled with macOS) passes the JAR file to JRE, or JVM, which runs the file. If you have JRE installed and set as the default program associated with JAR files, you can simply double-click the JAR file to run it. JAR files are typically used to distribute applications that can be run with the Oracle Java Runtime Environment (multiplatform).
