Both languages are built with the intention of simplifying the development of apps. You need to make a fair choice between them depending upon your needs.

In case you are looking at an enterprise level application which has portability and is platform independence drawing high number of users, then might want to choose Java.

On the other hand, if you are looking at developing web services, highly secure applications which would be feature packed with a rich GUI. You might want to choose .NET.

Be wise… Be decisive…
