import java.time.LocalTime;
public class LocalTimeTest {

    public static void main(String[] args) {
        LocalTime now = LocalTime.now();
        System.out.println("当前系统时间：" + now);

        //修改小时
        LocalTime localTime = now.withHour(10);
        System.out.println("修改后的小时：" + localTime);

        //修改分钟
        LocalTime newMinute = now.withMinute(2);
        System.out.println("修改后的 分钟：" + newMinute);

        //修改秒
        LocalTime newSecond = now.withSecond(50);
        System.out.println("修改后的秒：" + newSecond);

        //修改纳秒
        LocalTime newNano = now.withNano(10);
        System.out.println("修改后的纳秒：" + newNano);

        //增加小时
        LocalTime plusHours = now.plusHours(1);
        System.out.println("增加小时：" + plusHours);
    }
