How do you handle internationalization for "Your input 'xyz' is excellent!"

I would like to know what is the right way to handle internationalization for statements with runtime data added to it. For example 1) Your input "xyz" is excellent! 2) You were "4 years" old when you switched from "Barney and Freinds" to "Spongebob" shows.

The double quoted values are user data obtained or calculated at run time. My platforms are primarily Java/Android. A right solution for Western languages are preferred over weaker universal one.
