Did you have a look in the wiki?
Did you ensure that no app exists that already fulfills your requirement?
If you just need an app that downloads tile or vector data for offline usage,
plenty of applications exist for various platforms. No need to dev your own.

Have a look at the popular OsmAnd and its offline data, for instance.

should also help. Be aware that excessive tile downloading at high speeds
will probably get you banned or throttled, so use sensible connection
parameters while downloading.

Can you describe better your use case?

Do you want to:

1. download some tiles and work with them offline (while disconnected from network)? You can always provide ​file:/// URL to JMapViewer, and work with tiles on your local drive
2. download some tiles online, but be resilent to network outages and cache downloaded tiles, so when they are evicted from memory, have the ability to load them from disk? You would need then to include some code from Apache JCS and JOSM and adapt TMSCachedTileLoader class for your needs

Or something else?
