-cp means classpath for zip/jar files

java -cp abc.jar?



will look in abc.jar (of course your command is incomplete, you have to provide one more ARGUMENT i.e. an executable class name)

It lets you set the classpath to use for searching for class files. you can also type in java -? to get help on what options are available and what they mean.
