OK,
Thanks.
Python made the code easier and shorter using that syntax, but if java takes
performances just to do the same,
I guess it would be better to use the + syntax:
String firstName = "Cedric";
String a = "Hello " + firstName;
In case of many elements to put in the string, it will render something like
this:
String a = "Hello " + firstName + ", how are you ? Did you have a good day on " +
day + ". I guess it will be
better on " + date.toString() + ". See you".
Thanks
string concatenation using + is rather expensive, but it depends where
you use it.
for large strings I usually do:
StringBuilder s = new StringBuilder();
s.append("...");
return s.toString()
and to do "real" formatting:
String.format("... %s, ... ", args)
which is closest to python's %
