获取日期

String date = new SimpleDateFormat("yyyy-MM-dd",   Locale.getDefault()).format(new Date());

为了得到时间

String time = new SimpleDateFormat("hh:mm", Locale.getDefault()).format(new Date());

来获取日期和时间

String dateTime = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss", Locale.getDefaut()).format(new Date());

快乐编码:)

public static void main(String[] args) 
{
    Date d = new Date();
    SimpleDateFormat form = new SimpleDateFormat("dd-mm-yyyy hh:mm:ss");
    System.out.println(form.format(d));
    String str = form.format(d); // or if you want to save it in String str
    System.out.println(str); // and print after that
}

使用DateFormat#format方法将日期转换为字符串:

String pattern = "MM/dd/yyyy HH:mm:ss";

// Create an instance of SimpleDateFormat used for formatting 
// the string representation of date according to the chosen pattern
DateFormat df = new SimpleDateFormat(pattern);

// Get the today date using Calendar object.
Date today = Calendar.getInstance().getTime();        
// Using DateFormat format method we can create a string 
// representation of a date with the defined format.
String todayAsString = df.format(today);

// Print the result!
System.out.println("Today is: " + todayAsString);

从http://www.kodejava.org/examples/86.html

Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String s = formatter.format(date);

common -lang DateFormatUtils充满了好东西(如果你的类路径中有common -lang)

//Formats a date/time into a specific pattern
 DateFormatUtils.format(yourDate, "yyyy-MM-dd HH:mm:SS");

让我们试试这个

public static void main(String args[]) {

    Calendar cal = GregorianCalendar.getInstance();
    Date today = cal.getTime();
    DateFormat df7 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    try {           
        String str7 = df7.format(today);
        System.out.println("String in yyyy-MM-dd format is: " + str7);          
    } catch (Exception ex) {
      ex.printStackTrace();
    }
}

或者效用函数

public String convertDateToString(Date date, String format) {
    String dateStr = null;
    DateFormat df = new SimpleDateFormat(format);

    try {
        dateStr = df.format(date);
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    return dateStr;
}

从转换日期到字符串在Java
