A list of strings.

Gets the first token in a string.

Parameters:

string - The string to tokenize.

delimiters - The characters any of which delimit tokens.

Returns:

The string which is the first token.

lastToken

public static java.lang.String lastToken(java.lang.String string,
                                         char delimiter)

Gets true if a string matches a pattern which may include wildcard characters. "*" matches zero or more of any character, "?" matches exactly one occurrence of any character. A wildcard character may be escaped so that it is matched as an ordinary character by prefixing it with a backslash ("\"). A backslash may be escaped by prefixing it with a backslash also.

Parameters:

pattern - The pattern to match against, containing wildcards.

Returns:

true if the string matches the pattern, false otherwise.

toString

public static java.lang.String toString(java.lang.Object object)

toString

public static java.lang.String toString(java.lang.String message,
                                        java.lang.Object[] arguments)

Gets a formatted string from a template string and an array of arguments. The formatted string is the template string with occurrences of "{0}", "{1}", etcetera, replaced with the String representation of the corresponding argument.

append

public static void append(java.lang.StringBuffer buffer,
                          java.lang.String message,
                          java.lang.Object[] arguments)

Appends a formatted string from a template string and an array of arguments to a StringBuffer. The formatted string is the template string with occurrences of "{0}", "{1}", etcetera, replaced with the String representation of the corresponding argument.

append

public static java.lang.StringBuffer append(java.lang.StringBuffer buffer,
                                            java.lang.Object object)

Appends a string representation of an object to a string buffer. The major difference between this method and String.valueOf is that this method formats arrays as collections. To catch arrays that are elements of collections, it also does its own formatting for Collection and Map classes.
