Method Detail

charArrayToString

public static java.lang.String charArrayToString(char[] chars)

converts a char[] to a string. Note the toString() method of a char[] does not do this.

Parameters:

chars - the char array

Returns:

the equivalent string, or null if an error occurred

charArrayToString

public static java.lang.String charArrayToString(char[] chars,
                                                 int start,
                                                 int end)

converts part (or all) of a char[] to a string. Note: the toString() method os a char[] does not do this.

Parameters:

chars - the char array

start - starting point

end - ending point

Returns:

the string for the section of chars; or null, if an error occurred

replaceSubstringAtLocation

public static java.lang.String replaceSubstringAtLocation(java.lang.String baseString,
                                                          java.lang.String oldSubstring,
                                                          java.lang.String newSubstring,
                                                          int startPoint)

Replace a substring at a specific location in a String with a new substring. Note that the location is needed because the base string could include multiple instances of the substring to be replaced.

Parameters:

baseString - the basic string in which the substitutions are made

oldSubstring - the substring to be replaced

newSubstring - the replacement substring

startPoint - location of the substing

Returns:

the new string with the substitution completed

truncate

public static java.lang.String truncate(java.lang.String text,
                                        int count)

Truncates count number of bytes from the back (right end) of a string

Parameters:

text - the string to truncate

count - how much to truncate

Returns:

the truncated string or, in the case of error, the original string.

lop

public static java.lang.String lop(java.lang.String text,
                                   int count)

Truncates count number of bytes from the front (left end) of a string

Parameters:

text - the string to truncate

count - how much to truncate

Returns:

the truncated string or, in the case of error, the original string.
