Well the basic purpose of not using the String objects is because they are
immutable, eat up a lot of memory and the whole exercise turns out to be
inefficient. Therefore it is beter to use the StringBuffer Object.
It would make no difference if you would create a number of StringBuffer
Objects to display your output as you would still be creating a lot of
objects which would inturn use a lot of memory and this was exactly the
reason why you were advised not to use the String Objects.
Best thing to do would be to create a single StringBuffer Object use the
append method for adding data ( as you are already doing ) and then call
the toString() method on the StringBuffer Object to display the contents.
Have a nice day.

Subject: StringBuffer
> Hi,

> I have a question regarding String and StringBuffer class. Recently I

> System.out.println(new

> ----
> System.out.println(new
> StringBuffer("test3").append("test4").append("test5"));

> Now my question is that whether I should have one StringBuffer variable,
> append it and then displays or everytime "new StringBuffer". Which way
