#23030 — Printing Out appended list

Dear Group, 

If I try to append the strings in sb within a loop, where strings are getting generated from loop, --this part is getting fine, but the problem is how I can take out the print of the "sb" portion. 

 for (loop condition) {
    StringBuilder sb = new StringBuilder();
    sb.append("some string");
    . . .
    sb.append(anotherString);
    }

If any one of the esteemed members can kindly suggest.

Regards,
Subhabrata.

I don't understand what is being asked.  What is "take out the print"?

What does System.out.println( sb ); give you?  What do you want different?

Difficult to know exactly what you mean here but I'll take a shot

StringBuilder sb = new StringBuilder();
for(condition){
    sb.append("some string");
    ...
}
System.out.printf("%s\n", sb.toString());

--or, slightly more disturbingly --

StringBuilder buffer = new StringBuilder();
for(condition){
    StringBuilder sb = new StringBuilder();
    sb.append("whatever");
    ...
    buffer.append(sb.toString());
}
System.out.printf("%s\n", buffer.toString());

can't see the point of this second example although it appears to meet 
your original criteria of creating a new builder for each iteration of 
the loop.

     This pseudocode shows no printing at all, so I guess you have
already found a way to "take out the print."  What "print" are you
talking about, and why do you want to get rid of it?

     Maybe if you showed actual code instead of pseudocode it would
be easier for us to understand your intent.

I think he means "extract the answer from the StringBuilder" analogous
to printing out the final result of some calculation.

I am making a wild guess that what you want has nothing to do with
putting ink on paper.

  String result = sb.toString();
