Programming is always about maintainability. The code you wrote should be able to be modified by a developer coming in 100 years after you.

Maintainability rely heavily in code readability. Second one is more readable than the first one.

And further more second one is much more flexible. In the sense if you want to change the datatype of two in second method it is much easier than first method.

There is no difference. Compiler will do it in the best way, so in byte code you would have always (in both cases):

   // access flags 0x0
   Ljava/lang/String; one

   // access flags 0x0
   Ljava/lang/String; two

   // access flags 0x0
   Ljava/lang/String; Three

Going this way, use what is more appriopriate in your project. Don't care about the memory!

Both methodologies are equivalent, although the first one might be less readable under some circumstances. What you should not do is to declare a variable starting with an upper-case letter, as you do with your 3rd String.
