SimpleDateFormat ft = new SimpleDateFormat("E yyyy.MM.dd 'at' hh:mm:ss a zzz");
String reportDate = ft.format(dNow);
public void LoadDate() {

System.out.println("Current Date: " + reportDate);
}

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");

使用Date()获取当前日期时间
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));
使用Calendar()获取当前日期时间
get current date time with Calendar()
//get current date time with Calendar()
Calendar cal = Calendar.getInstance();
jTextField3.setText(dateFormat.format(cal.getTime()));
