If you only have one reference to a string and you concatenate another string to the end, CPython now special cases this and tries to extend the string in place. The end result is that the operation is amortized O(n). e.g. used to be O(n^2), but now it is O(n). From the source (bytesobject.c): It’s … Read more
http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#intern() Basically doing String.intern() on a series of strings will ensure that all strings having same contents share same memory. So if you have list of names where ‘john’ appears 1000 times, by interning you ensure only one ‘john’ is actually allocated memory. This can be useful to reduce memory requirements of your program. But … Read more

You can also use the StringBuilder class which is mutable. It has the method deleteCharAt(), along with many other mutator methods. Just delete the characters that you need to delete and then get the result as follows: This avoids creation of unnecessary string objects.
