Method Details

public static final String replace(String line,
 String oldString,
 String newString)

Replace oldString occurrences with newString occurrences of the String line and return the result.

isEmpty

public static boolean isEmpty(String value)

Return true if String value is null or empty.

capitalize

public static String capitalize(String str)

Capitalizes all the whitespace separated words in a String. Only the first letter of each word is changed.

Whitespace is defined by Character.isWhitespace(char). A null input String returns null. Capitalization uses the unicode title case, normally equivalent to upper case.

 WordUtils.capitalize(null)        = null
 WordUtils.capitalize("")          = ""
 WordUtils.capitalize("i am FINE") = "I Am FINE"
 

Parameters:

str - the String to capitalize, may be null

Returns:

capitalized String, null if null String input

capitalize

public static String capitalize(String str,
 char[] delimiters)

Capitalizes all the delimiter separated words in a String. Only the first letter of each word is changed.

The delimiters represent a set of characters understood to separate words. The first string character and the first non-delimiter character after a delimiter will be capitalized.

A null input String returns null. Capitalization uses the unicode title case, normally equivalent to upper case.

 WordUtils.capitalize(null, *)            = null
 WordUtils.capitalize("", *)              = ""
 WordUtils.capitalize(*, new char[0])     = *
 WordUtils.capitalize("i am fine", null)  = "I Am Fine"
 WordUtils.capitalize("i aM.fine", {'.'}) = "I aM.Fine"
 

Parameters:

str - the String to capitalize, may be null

delimiters - set of characters to determine capitalization, null means whitespace

Returns:

capitalized String, null if null String input
