                                                  java.lang.String delim)

Take Collection l and build a String of the elements in l delimited by d.

replace

public static java.lang.String replace(java.util.Map map,
                                       java.lang.String text,

                                       java.lang.String tagEnd)

Replaces all instances of keys with values in map. for each key, we prepend tagStart and append tagEnd

replace

public static java.lang.String replace(java.util.Map map,
                                       java.lang.String text)

                                       java.lang.String replacement,
                                       java.lang.String text)

Replaces all instances of pattern in text with replacement.

extend

                                        java.lang.String s)

Return a new array with s appended to a.

extend

public static java.lang.String[] extend(java.lang.String[] a,
                                        java.lang.String[] s)

Return a new array with s appended to a.

initCap

public static java.lang.String initCap(java.lang.String s)

Sets all Characters to Lower and then Capitaizes the First Leter.

parseMap

public static java.util.Map<java.lang.String,java.lang.String> parseMap(java.lang.String s)

Parse a space delimited String into a map eg key=1 hp=25 would parse into a map with keys key and hp, and values 1 and 25 respectively.

parseMap

public static java.util.Map<java.lang.String,java.lang.String> parseMap(java.lang.String s,
                                                                        java.lang.String delimiter)
