Methods

o sequence 
 public Enumeration sequence()
Returns an enumeration of sequential characters starting at 'a' and ending at 'z'.

Returns:

o sequence 
 public Enumeration sequence(char c)
Returns an enumeration of sequential characters starting at the given c value.

Parameters:
c - the start of the generated sequence.
Returns:
an enumeration of sequential Char objects starting at the value of c.
o sequence 
 public Enumeration sequence(Object startValue) throws IllegalArgumentException
Returns an enumeration of sequential characters starting at the given start character. The sequence continues to either 'z' or 'Z', depending on the given start character.

Parameters:
startValue - the Char object representing the start of the generated sequence.
