Methods

public static boolean isValidDate(String dateString, String dateFormatPattern)

Returns true if the specified date string represents a valid date in the specified format. The dateFormatPattern is a String specifying the format to be used when parsing the dateString. The pattern is expressed with the pattern letters defined for the java.text.SimpleDateFormat class.

public static boolean isValidEmailAddr(String emailAddrString)

Returns true if the email string contains only one at-sign, except as the first or last character, no whitespace and at least one dot after the at-sign, except as the first or last character. Note! This rule isn’t always correct (e.g., on an intranet it may be okay with just a name) and it doesn’t guarantee a valid Internet email address, but it takes care of the most obvious Internet mail address format errors.

public static boolean isValidInteger(String numberString, int min, int max)

Returns true if the specified number string represents a valid integer in the specified range.

public static boolean isValidString(String value,

String[] validStrings, boolean ignoreCase)
