A:
According to wikipedia, JAR is an archive format used by Java to combine classes into one application or library.
It is essentially a zip archive with some additional information, such as a manifest.
To create one just use jar command inside the folder where you store your classes.
jar -cf my.jar *.class

jar is a command line tool, part of the Java, the same as java and javac commands. There is a tutorial at sun's website http://java.sun.com/docs/books/tutorial/deployment/jar/build.html
