Java concatenate strings vs static strings

Question

I try to get a better understanding of Strings. I am basically making a program that requires a lot of strings. However, a lot of the strings are very, very similar and merely require a different word at the end of the string.

E.g.

String one = "I went to the store and bought milk"
String two = "I went to the store and bought eggs"
String three = "I went to the store and bought cheese"

So my question is, what approach would be best suited to take when dealing with strings? Would concatenating 2 strings together have any benefits over just having static strings in, say for example, performance or memory management?

E.g.

String one = "I went to the store and bought "
String two = "milk" 
String three = "cheese"
String four = one + two
String five = one + three

I am just trying to figure out the most optimal way of dealing with all these strings. (If it helps to put a number of strings I am using, I currently have 50 but the number could surplus a huge amount)

As spooky has said the main concern with the code is readability. Unless you are working on a program for a phone you do not need to manage your resources. That being said, it really doesn't matter whether you create a lot of Strings that stand alone or concatenate a base String with the small piece that varies. You won't really notice better performance either way.
