StringBuilder Class
Java StringBuilder class is used to create mutable (modifiable) String objects.
StringBuilder class is the same as StringBuffer class except this class is not thread safe.
StringBuilder have same constructor as StringBuffer.
StringBuilder have same metod like StringBuffer only change
StrignBuffer all method are synchronization.
in StringBuilder have normal method that’s why StringBuilder is not thread safe.
but if we talk performance wise
1. StrignBuffer slower.
2. StringBuilder faster compare to StringBuffer.
All String , StringBuffer and StringBuilder classes are final class we can’t extend this classes.
