Often we need to find the class or classpath exists in a java jar file or due to some Error like "could not load X class from Y module" at that time we need to check the available classes in jar file. For that one of the common method is
java -cp path_to.jar <Tab>
For example, I have a jar file(hive-beeline-3.1.3.jar) at path hive/lib/. Using the command, when I press Tab, it is showing all the classes which it have.
Thanks
