Perhaps you'd have some luck using Cindy's member number as one of the search parameters. It's 3498.

Object type Comparision
-->> immutable (Value once assigned cannot be modified)
-->> mutable (Value can be modified).
is better when u compare String with
in string manipulation that is
String str = "Hello";
str = str+"World" ;
sbstr = new
if we look at the above example the major and hidden difference is internally how JVM handles the string manipulation....
when we say str = str+"World";
xxx = new
str = xxx.toString();
Now u can make out that internally there is a overhead of converting the String str to
and applying append method on that and finally it is assigned backto the str the modifed str....
