Class StringBuffer ( java.lang.StringBuffer )

StringBuffer

The StringBuffer class is an alternative to the String class. You can add, insert, or append new contents into a string buffer, whereas the value of a String object is fixed once the string is created.

StringBuffer is mutable.StringBuffer is a synchronized and allows us to mutate the string. StringBuffer has many utility methods to manipulate the string. It can change in terms of length and content.
StringBuffers are thread-safe,meaning that they have synchronized methods to control access,so that only one thread can access a StringBuffer object's synchronized code at a time.

Thus, StringBuffer objects are generally safe to use in a multi-threaded environment where multiple threads may be trying to access the same StringBuffer object at the same time.

StringBuffer declaration :

public final class StringBuffer 
extends Object implements Serializable, CharSequence
