2.system获取

long current=System.currentTimeMillis();//当前时间毫秒数

3.日期类

Calendar rightNow = Calendar.getInstance(); // 子类对象// 获取年int year = rightNow.get(Calendar.YEAR);// 获取月int month = rightNow.get(Calendar.MONTH);// 获取日int date = rightNow.get(Calendar.DATE);// 获取几点int hour = rightNow.get(Calendar.HOUR_OF_DAY);// 获取上午下午int moa = rightNow.get(Calendar.AM_PM);if (moa == 1) {System.out.println("下午");} else {System.out.println("上午");}System.out.println(year + "年" + (month + 1) + "月" + date + "日" + hour + "时");rightNow.add(Calendar.YEAR, 5);rightNow.add(Calendar.DATE, -10);int year1 = rightNow.get(Calendar.YEAR);int date1 = rightNow.get(Calendar.DATE);System.out.println(year1 + "年" + (month + 1) + "月" + date1 + "日" + hour + "时");
