DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
get current date time with Date()
//get current date time with Date() Date date = new Date(); System.out.println(dateFormat.format(date)); jTextField3.setText(dateFormat.format(date));get current date time with Calendar()
//get current date time with Calendar() Calendar cal = Calendar.getInstance(); jTextField3.setText(dateFormat.format(cal.getTime()));
使用 Date() 获取当前日期时间
//get current date time with Date() Date date = new Date(); System.out.println(dateFormat.format(date)); jTextField3.setText(dateFormat.format(date));使用 Calendar() 获取当前日期时间
//get current date time with Calendar() Calendar cal = Calendar.getInstance(); jTextField3.setText(dateFormat.format(cal.getTime()));
