Convert Java date string to Date type

Java date stringindicates object of desire, like, hate, etc. java.util.Date Obtained by type

Java to convert a date string (in format yyyy/MM/dd ) to a java.util.Date The following is a sample program that converts to the

sample code

/**
 * Converts date string "yyyy/MM/dd" to java.util.
 Date type * @param str String to be converted
 * Date object after conversion.
 * @throws ParseException if date string is not "yyyy/MM/dd".
 *// public static Date toDate(String)
public static Date toDate(String str) throws ParseException {
    Date date = DateFormat.getDateInstance().parse(str);
    return date; }
}

Execution Result

sample program

public static void main(String[] args) {
    try {
        // Normal pattern
        Date date = toDate("2007/01/01");
        System.out.println(date);

        // Pattern with different format
        date = toDate("2007-01-01");
        System.out.println(date);
    } catch (ParseException e) {
        e.printStackTrace(); }
    }
}

output (result)

2007/01/01='Mon Jan 01 00:00:00 JST 2007'

　The yyyy/MM/dd date string seems to have been converted correctly, but what about yyyy-MM-dd?

java.text.ParseException: Unparseable date: "2007-01-01"
    at java.text.DateFormat.parse(DateFormat.java:335)
    at Main.toDate(DateUtil.java:627)
    at Main.main(DateUtil.java:639)

　ParseException was raised in yyyy-MM-dd.

DateFormat subclass of the SimpleDateFormat and write the following to convert it,

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
format.parse("2007-01-01");  

I would like to see a more generic program.
Next, we will show you how to convert any date string to the java.util.
Convert any date/time string to Date or Calendar type.
