parse

public Date parse(String source)
           throws ParseException

    Parses text from the beginning of the given string to produce a date. The method may not use the entire text of the given string.

    See the parse(String, ParsePosition) method for more information on date parsing.

    Parameters:
        source - A String whose beginning should be parsed. 
    Returns:
        A Date parsed from the string. 
    Throws:
        ParseException - if the beginning of the specified string cannot be parsed.

parse

public abstract Date parse(String source,
                           ParsePosition pos)

    Parse a date/time string according to the given parse position. For example, a time text "07/10/96 4:5 PM, PDT" will be parsed into a Date that is equivalent to Date(837039928046).

    By default, parsing is lenient: If the input is not in the form used by this object's format method but can still be parsed as a date, then the parse succeeds. Clients may insist on strict adherence to the format by calling setLenient(false).

    Parameters:
        source - The date/time string to be parsed
        pos - On input, the position at which to start parsing; on output, the position at which parsing terminated, or the start position if the parse failed. 
    Returns:
        A Date, or null if the input could not be parsed
