Solution
The incorrect form of StringBuffer class constructor is:
StringBuffer(int size , String str)
This is not a valid constructor for the StringBuffer class in Java. The valid constructors are:
- StringBuffer(): Constructs a string buffer with no characters in it and an initial capacity of 16 characters.
- StringBuffer(int capacity): Constructs a string buffer with no characters in it and the specified initial capacity.
- StringBuffer(String str): Constructs a string buffer initialized to the contents of the specified string.
