Method Detail

compareStrings

public static int compareStrings(java.lang.String a1,
                 java.lang.String a2)

Compare two string for sorting.

If both strings are numeric (ex: 15 and 110), sort them numerically rather than alphabetically.

If both strings start with the same alphabetic prefix and end with a number (ex: PARM_15 and PARM_110), then sort the last part numerically.

Otherwise, sort the two strings alphabetically.

Parameters:

a1 - The first string to compare

a2 - The second string to compare

Returns:

the value 0 if a1 is equal to a2; a value less than 0 if a1 is lexicographically less than a2; and a value greater than 0 if a1 is lexicographically greater than a2.

public static boolean isNumber(java.lang.String val)
