plusHours(long hoursToAdd):增加指定小时数后的时间对象。 minusMinutes(long minutesToSubtract):减去指定分钟数后的时间对象。 下面是这些方法的使用示例: LocalTimetime=LocalTime.of(20,15,30);inthour=time.getHour();intminute=time.getMinute();intsecond=time.getSecond();System.out.printf("hour: %d,...

Java 8 提供了更好的 plusHours() 方法替换 add() ,并且是兼容的。注意,这些方法返回一个全新的LocalTime实例,由于其不可变性,返回后一定要用变量赋值。 1//增加小时2publicvoidplusHours(){3LocalTime time =LocalTime.now();4LocalTime newTime = time.plusHours(2);//增加两小时5System.out.println("Tim...
