Regarding StringBuilder

In the above code when String s1 and s2 are appended to StringBuilder, will JVM create a new array of the char and append it to the StringBuilder or will the StringBuilder hold reference to the String objects.

Thank you

Serious question: why would it matter?

I agree wtih Bear that it doesn't matter for the exam. If you are curious, you can look at an implementation and see that the Strings are stored as a char[] not a String[]. When the array fills up , a bigger one is created.
