Solution

identify:
Returns the lower case equivalent of the argument -- toLowerCase ()
A named object of the String class -- String variable
Change the length of a string in a StringBuilder object
Determines whether a specific character occurs within a String -- indexOf()
Takes two integer arguments: a start position and an end position -- substring()
Takes a String argument and returns its double value -- ParseDouble()
A memory block -- buffer
Add characters to the end of a StringBuilder object -- append()
Add characters at a specific location within a StringBuilder object -- insert()
