Thanks for changing your name.
yes, "def" and "abc" will be added to the string pool. EVERY string literal is put in the pool, and you don't have control over this.
Using a StringBuffer actually causes FEWER strings to be abandoned in the heap. A String is immutable. Once it is created, it can never be changed. so when you concatenate Strings, new Strings are created all over the place. each time you use the "+" operator, it's a new String, so
stringone + stringtwo + stringthree + string4;
creates (i believe) 3 strings - two temporary ones that are lost almost as soon as they are created, and one we keep. That is in addition to the four strings we have already created.
The code s1 += "winter" doesn't change the String s1 points to, but creates a brand new string and re-assigns the reference to that new string.
a StringBuffer would change the underlying object itself, thus not causing the object to be lost.
