If it's still relevant I could take it.

Hi @vcvitaly, yes, this is still relevant so will assign the issue to you. Thank you for volunteering!

As this issue still persist there so can i get a chance to have a look on it, if it available.

[vcvitaly]

@himanshu211raj Yes, please do. I haven't had a chance to work on it.

[himanshu211raj]

As i am recently started using eclipse can anyone guide me how can i proceed toward this?

[donraab]

@himanshu211raj When you refer to Eclipse in your comment do you mean Eclipse Collections or the Eclipse IDE? The two are unrelated. Eclipse Collections is a Java Collections library and can be used in any Java program.

If you mean Eclipse Collections, you can learn more about how to get started here.

@himanshu211raj you should update documentation on the subject in a way similar to documentation here:
https://github.com/eclipse/eclipse-collections/blob/master/docs/guide.md#-primitive-collections

So basically try using them yourself and then add some examples.
