jar files

[oiram]

Hello:

When I make a jar -tvf of some files I see the following:

name.class
name$1.class
name$2.class

Does any of you know what means the $1, $2 ... after the name of the files.

Thanks,
Mario.

You get one of those "name$n.class" files for each anonymous inner class of class "name".

HI Mario,

How to create a JAR file

To make a JAR file:

JAR CVF my.jar *.class

You have to indicate which class is the entry point in the JAR file. You are doing this by adding a Main-Class header to the JAR file's manifest. The header takes the form:

Note: Note classes with the name *$1.class is automatically created when you compile. These files must be included in the JAR file.

Hope it helps,

Robert-Jan.

Hi,

One more thing:

You can re-create the .class file again in case you loose them. Just recompile the .java files and create jar files if you want to.
