Question

with which character does java fill the empty spaces in a stringbuffer object?​

Answer 1

Answer:

>>> StringBuffer is a peer class of String that provides much of the functionality of strings. String represents fixed-length, immutable character sequences while StringBuffer represents growable and writable character sequences.

>>>> StringBuffer may have characters and substrings inserted in the middle or appended to the end. It will automatically grow to make room for such additions and often has more characters preallocated than are actually needed, to allow room for growth.

StringBuffer Constructors

StringBuffer( ): It reserves room for 16 characters without reallocation.
