Method Detail

glue

public static String glue(String first,
                          String second)

useful for gluing URLs together, since this uses '/' as the glue character to call glue(String,String,String)

glue

public static String glue(String first,
                          String separator,
                          String second)

Returns:

first glued to second with the separator string, at most one time - useful for appending paths.

joinArray

public static String joinArray(String s,
                               Object... a)

join

public static String join(String delim,
                          List<String> l)

chop

public static String chop(String source,
                          int length)

squeeze

public static String squeeze(String s)

Remove all whitespace from a String.

now

public static Long now()

Milliseconds from start time as defined by the Date class.

nowLocale

public static String nowLocale()

isEmpty

public static boolean isEmpty(String str)

Handles null strings as empty.

isBlank

public static boolean isBlank(String str)

nulls, empty strings, and empty after trim() are considered blank.

notEmpty

createSortedCaseInsensitiveMap

public static Map createSortedCaseInsensitiveMap()

Creates a TreeMap with a case-insenstive collator using the US Locale.

isTrue

public static boolean isTrue(String test)

Handles null strings as false.

searchAndReplace

public static String searchAndReplace(String source,
                                      String find,
                                      String replace)

searchAndReplaceWithQuoteReplacement

public static String searchAndReplaceWithQuoteReplacement(String source,
                                                          String find,
                                                          String replace)
