Join Peggy Fisher for an in-depth discussion in this video Creating and importing JAR files, part of Java Essential Training for Students.
- Now I'd like to talk about the term "J - A - R."…J - A - R is referred to as a "JAR" file,…and the "JAR" in JAR file stands for "Java Archive."…It's commonly used to combine several classes…into one compressed file.…JAR files are created either using the utility…jar.exe that's provided in the Java JDK,…or you can create your JAR file in your IDE,…your integrated development environment.…In this section I will describe creating JAR files…from both the command line, and in the IDE.…
Let's start with a command line version.…Before making our JAR file, we need to get all our classes…and manifest file together in one directory.…Let's use windows explorer to create a new…folder called "Geometry," inside our "my java" folder.…Now we can copy all the files from the 04_02 exercise folder…into the geometry folder.…We're all set now, we can work with the files…in the console window to make our JAR file.…
To make the JAR file runnable, you need to create a manifest…file that specifies which class contains the main method.…
