It’s different, rather than easier.
The reason the Java jobs are listed against frameworks is becuase Java has tons of frameworks and design patterns ready to be used to make things easier to maintain. The design patterns and frameworks are starting to appear more in .NET now too, so expect to see jobs changing to look more like those Java jobs.
There are just as many patterns and practices in both worlds – but they are more established in the Java community (the Java employer will push them onto you, you will find yourself pushing your .NET employer).
Largely, Java vs .NET is syntax. Do either (do both!). But be aware of the patterns and frameworks as they’ll really help you to write better code.
