A thread-safe, mutable sequence of characters. A string buffer is like a String, but can be modified. At any point in time it contains some particular sequence of characters, but the length and content of the sequence can be changed through certain method calls. String buffers are safe for...
Thread-Safety Difference: The difference betweenStringBufferandStringBuilderis thatStringBufferis thread-safe. So when the application needs to be run only in a single thread then it is better to useStringBuilder.StringBuilderis more efficient thanStringBuffer. Situations: If your string is not going ...

StringBuffer is mutable and thread safety as all the methods of this class are synchronized, so we should prefer to use it in multithreaded application StringBuilder is mutable but not thread safe as methods of this class are not synchronized, so we should prefer to use it in single ...
This class is designed for use as a drop-in replacement for StringBuffer in places where the string buffer was being used by a single thread (as is generally the case). Where possible, it is recommended that this class be used in preference to StringBuffer as it will be faster under ...

because sb.toString() is called implicitly, as it is with any other object in a println() invocation. Note: There is also a StringBuffer class that is exactly the same as the StringBuilder class, except that it is thread-safe by virtue of having its methods synchronized. Threads will be...
