String objects ..

[Soumy Kumar]

How many string objects are created prior to the output st..
and totally??

 
 
String s1 = "spring ";
String s2 = s1 + "summer ";
s1.concat("fall ");
s2.concat(s1);
s1 += "winter ";
System.out.println(s1 + " " + s2)
 

I thought the answer is 8 and 10.

But
"java.lang.String#concat(String). i.e. A String instance is created and returned, however, the return value is ignored and therefore, is not counted in the total count of String instances."

According to the above quote.
the answer will me 6 and 8..

Correct answer needed ???

I'm not sure, but i guess that the above statement does not actually refer to the number of Strings created. If "the return vale is ignored and therefore, not counted in the total number os instances", it doesn't mean that the Strings were not created. It just means that they were ignored and lost.

So do I. I may agree with the above statement and also stick with the opinion that 8 String objects were created prior to the last line and 10 Strings objects were created in total. However, i also agree that the above statement may cause some misunderstanding.
