new String 2005-10-16 - By Frans Verhoef

Hi,
String s1 = "test" is definitely preferred, as the other version creates two
objects containing "test". Also, when you assign many times "test" to a string
object, than only one string is created in memory, while if you use new String(
"test"), a new string is created every single time.
For example:
String[] s = new String[1000000];
for (int i=0; i<1000000; i++) s[i] ="test"; // uses hardly any memory
for (int i=0; i<1000000; i++) s[i] = new String("test"); // uses lots of memory
, as each time a new string is created
Cheers,
Frans
