In Java, how is an Array of objects garbage collected? -

-

when array of objects not referenced anymore, objects in array garbage collected too? (assuming no variables referencing elements)

in page, http://java.sys-con.com/node/37613 says - "the biggest danger placing object collection , forgetting remove it. memory used object never reclaimed."

if make sure nullify references, why memory unclaimed?

thanks

yes.

"the biggest danger placing object collection , forgetting remove it. memory used object never reclaimed."

this when are holding reference collection. example, if have map in put key-value , forget remove stays there ever. think http sessions, if use in servercontext or such @ start of request using session id key fail remove @ end of request processing..
