User cannot force the garbage collection, instead user can send a request to JVM asking for doing the garbage collectin with System.gc() method.

Once, JVM recieves the gargabe collection request and if memory really needs to be collected (like if memory out of condition situations occur) then JVM automaically runs the thread to do the garabge collection.
