NO.125 Which statement initializes a stringBuilder to a capacity of 128?

 StringBuilder sb = new String (“128”);

 StringBuilder sb = StringBuilder.setCapacity (128);

 StringBuilder sb = StringBuilder.getInstance (128);

 StringBuilder sb = new StringBuilder (128);

StringBuilder(int capacity) Constructs a string builder with no characters in it and an initial capacity specified by the capacity argument. Note: An instance of a StringBuilder is a mutable sequence of characters. The principal operations on a StringBuilder are the append and insert methods, which are overloaded so as to accept data of any type. Each effectively converts a given datum to a string and then appends or inserts the characters of that string to the string builder. The append method always adds these characters at the end of the builder; the insert method adds the characters at a specified point.
