Doubt!!!!!!!!!!!!!!!!

[som]

Hi,

I am new to this group and learning Java, i have a doubt can any one
answere to this Q!

When we use the binary string concatenation operator (+), how many
String
Objects will be
created?

String zero = "zero";
char one = "1";
Float ten = 10.1;

String first = zero + "second" + 2 + "third" + 3 + one + ten;

At run time, when the above line of code is executed, how many objects
will
be created?

Regards
Soumya

You should also learn to use search engines in the internet. One of the
first hits when searching for "java string concatenation" is:

Thanks its really good, In shrt i wanted to know the imporatnce of +
operator in Java, now i am clear, it is used to concatenate strings and
in integer it acts as an additional operator!
