Method Detail

gsub

public static String gsub(String olds,
                          String news,
                          String text)

Substitute String "old" by String "new" in String "text" everywhere. This is static util function that I could not place anywhere more appropriate. The name of this function is from the good-old awk time.

Parameters:

olds - The String to be substituted.

news - The String is the new content.

text - The String in which the substitution is done.

Returns:

The result String containing the substitutions; if no substitutions were made, the result is 'text'.

indexOfWord

public static int indexOfWord(String text,
                              String word)

Searches for the first occurrence of a word, which must be surrounded by whitespace characters, in a text.

indexOfWord

public static int indexOfWord(String text,
                              String word,
                              int fromIndex)

Searches for the first occurrence of a word, which must be surrounded by whitespace characters, that appears in a text after 'fromIndex'.

lastIndexOfWord

public static int lastIndexOfWord(String text,
                                  String word)

Searches for the last occurrence of a word, which must be surrounded by whitespace characters, in a text.

lastIndexOfWord

public static int lastIndexOfWord(String text,

                                  int fromIndex)

Searches for the last occurrence of a word, which must be surrounded by whitespace characters, in a text. The algorithm searches the text backwards, starting from 'fromIndex'.
