Method Detail

incrementDigit

public static char incrementDigit(char c)

This method will perform an "increment" on a character. This method will sequence from 'a' to 'z' and then from '0' to '9'. After reaching '9', this method will return back to 'a'. This method will return 0 if the character is invalid. This method is case insensitive and will return a lower case incremented character.

Parameters:

c - The character to increment.

Returns:

The incremented character

incrementString

public static java.lang.String incrementString(java.lang.String str)

Provide a new String

Returns:

An incremented version of the passed in String object

incrementString

public static java.lang.String incrementString(java.lang.String str,
                                               int origLength)

Increment a string by appending a "_" + num to the end of it. If there is already an "_" at the end, the number is simply incremented. The original length of the string should be passed in so that the method will be able to determine if the "_" has already been added by this method or not.

Parameters:

str - the String to increment

origLength - the original length of the string to increment

Returns:

an incremented version of the string
