Method Detail

guardedSplit

public static java.lang.String[] guardedSplit(java.lang.String str,
                                              java.lang.String delim,
                                              char protect)

splits the string, guarding the space within protect. For example, if you have a comma-separable line with quoted fields, then this can be used so that a quoted field is not split on a comma: s= """2009,0,2,"Hot riser,spark",99""" could be split into five fields with guardedSplit(s,',','"').

Parameters:

str - the string to split.

delim - the delimiter we split on. (similar to s.split(delim,-2))

protect - character that blocks off delimiter, such as quote.

Returns:

spaces

public static java.lang.String spaces(int count)

Java 11 uses " ".repeat(n), so get Java 8 code ready for this. Also, this is efficient when there are 100 or fewer spaces, returning a subset of a constant string.

Parameters:

count -

Returns:

a string of length count spaces.

main

public static void main(java.lang.String[] args)
