new String 2005-10-17 - By Sonali Kansara

Yes Frans is right ......... its a concept called interned strings
...........
In case of compile time constant strings , a string available from the
pool is utilized instead of creating a new instance of the string .
So
String s1 = "Test5" ;
String s2 = "Test5" ;
String s3 = "Test"+"5" ;
int i = 5 ;
String s4 = "Test"+i ;
Here s1 , s2 , s3 are refering to the same instance of Test5 while s4
creates a new instance .

Sonali
