I want to use trove collections for my project but I was unable to use them by adding the jar file. https://bitbucket.org/robeden/trove/downloads
Can someone tell me how to use trove collections in my project?
Don't use trove-3.0.3-src.jar (this is source, not the binaries), instead use trove-3.0.3.jar from the "lib" directory. That should be placed in your classpath in whatever manner is appropriate for your development environment.
As has been mentioned, you can also download from Maven Central using Maven or Gradle (group: net.sf.trove4j artifact: trove4j).
