this kind of stupid how install multimap?

i need way store multiple values keys , map implementation isn't working

that class, multimap, not part of java standard library. part of apache commons, separate set of utility classes many java developers find useful. alternate multimap implementation (which recommend) available in guava, google's utility library.

in either case, in order utilize these classes, need download jar distributed project, , add together classpath when run program. can @ command line: including jars in classpath on commandline (javac or apt) or in eclipse: adding jar eclipse java library

if google phrases "installing jars" , "adding jars eclipse" you'll find many resources help if you're still struggling.
