Oh c'mon. Give the current Java compilers some more credit.

Most Java compilers, will optimize string concatenation whenever
possible. The examples given here falls into the category of simple
constant evaluation. The above example will be optimizied into:

String foo = "Hello World".

The same is true for Richards example.

Try it yourself. Compile a simple program "Hello " + "World" in it, then
use jad to decompile, or if you don't have it available, use strings(1)
on the resulting class file.
