WEBVTT 00:00.350 --> 00:00.890 Hi everyone. 00:00.890 --> 00:02.240 Welcome back to this tutorial. 00:02.240 --> 00:09.650 In this tutorial we will code and explore the next date and time library, which is the local date time. 00:10.010 --> 00:12.770 For this purpose, I'm going to create a class. 00:13.690 --> 00:19.300 Called local date time example. 00:20.540 --> 00:25.370 Let's make this class executable by adding public static void main method. 00:29.610 --> 00:34.080 Now, how can we create an instance of local date time? 00:34.710 --> 00:39.270 So the way to create is local date time dot now. 00:39.960 --> 00:41.550 So there are three different versions. 00:41.550 --> 00:44.720 For now, we are going to focus only on this version. 00:44.730 --> 00:49.530 The zone and Clock is something which will be covering when we cover the time zones. 00:50.730 --> 00:56.610 Dot Now this is going to give me an instance of local date time. 00:57.270 --> 00:59.130 Let's print this and check the machines. 00:59.130 --> 00:59.880 Current time. 01:01.270 --> 01:02.380 A secret date and time. 01:03.680 --> 01:04.730 I'm gonna turn. 01:04.730 --> 01:09.150 This is going to be local date and time. 01:09.170 --> 01:10.790 Let's run this and check the result. 01:11.800 --> 01:21.970 So the current date and time is 17th of July and the time is 555 and 54 seconds and 994 is a nanosecond 01:22.180 --> 01:22.690 precision. 01:22.690 --> 01:27.700 Let's take a look at what are the different ways of creating a local date time instance. 01:27.880 --> 01:34.240 The local date time instance as a factory method called off using which you can create a local date 01:34.240 --> 01:35.050 time instance. 01:35.050 --> 01:37.810 If you take a look at it, there are many options available here. 01:37.810 --> 01:42.190 What I'm going to do, I'm going to cover a few of these in this tutorial, but I would highly recommend 01:42.190 --> 01:46.290 you guys to go through and explore all the options that are available here. 01:46.300 --> 01:55.210 Now what I'm going to do, I'm going to pass the year and then the month and then the date and hour, 01:55.390 --> 01:58.810 minute, second and nanosecond. 02:00.700 --> 02:01.370 There you go. 02:01.400 --> 02:03.390 I'm going to put it down so that it will be visible. 02:03.560 --> 02:04.850 It'll fit the whole screen. 02:04.870 --> 02:09.100 Now what I'm going to do, I'm going to create a instance out of it. 02:09.430 --> 02:12.260 So this is a instance. 02:12.280 --> 02:22.510 Let's print this and check the result on how the local datetime instance looks like with the values, 02:22.510 --> 02:23.770 whatever that we passed. 02:23.800 --> 02:26.330 Let's run this when we run this. 02:26.350 --> 02:33.940 It gave you the result as as you see, this is the date which we passed here, meaning 2018, zero 321 02:33.940 --> 02:38.100 and T is a separator which splits the date from the time. 02:38.110 --> 02:45.550 And then we gave the time as 23 hours, 33 minutes and 33 seconds, powered by the nanosecond precision. 02:46.450 --> 02:50.020 Now let's explore another option, which is really, really handy. 02:50.050 --> 02:52.270 Local date time of. 02:52.450 --> 02:53.890 Take a look at the first option here. 02:53.890 --> 02:56.350 It takes in a local date and local time. 02:56.860 --> 02:57.850 Let's do this. 02:58.000 --> 02:59.550 I'm going to pass the local. 02:59.560 --> 03:05.260 I'm going to use the local date class and then call the now method, which is going to give me the current 03:05.260 --> 03:11.380 machines local date and followed by that I'm going to pass the local time dot now, which is going to 03:11.380 --> 03:15.790 return me the current machine's local time. 03:17.240 --> 03:19.760 This is going to return me, the local datetime instance. 03:19.760 --> 03:23.150 I'm going to give it a name and have it here. 03:24.260 --> 03:26.420 Let's print this and check the result. 03:26.660 --> 03:29.300 So I'm going to put it here. 03:29.750 --> 03:30.950 I'm going to put it here. 03:30.950 --> 03:34.940 So here we are passing the local date and time instance. 03:35.090 --> 03:42.200 That will give you the local date time together as a response, which is of type local date time and 03:42.200 --> 03:44.450 then give it a given name here. 03:44.480 --> 03:45.720 That's what we are printing here. 03:45.740 --> 03:47.870 Let's go ahead and run this and check the result. 03:51.040 --> 03:52.120 We take a look at it. 03:52.360 --> 04:00.700 The date and time is the current machines, local date and time, which is separated by a T so it combined 04:00.700 --> 04:04.330 and gave the local date time as a output. 04:04.360 --> 04:10.390 Now let's take a look at what are the different ways of getting the values from the local date time 04:10.390 --> 04:10.810 instance. 04:10.810 --> 04:14.020 Let's say I want to get the hour from the local date instance. 04:14.020 --> 04:14.920 How do we do it? 04:16.090 --> 04:24.130 Getting the time and date from local date time instance. 04:25.430 --> 04:28.280 So first thing is I want to get the ah, how do we do it? 04:29.270 --> 04:32.570 I'm going to have this text here. 04:34.320 --> 04:40.350 So I'm going to use this local datetime instance dot if I give the get. 04:40.380 --> 04:41.900 There are many options available. 04:41.910 --> 04:50.430 I have both the R and D methods available because this local date time is a combination of both date 04:50.430 --> 04:51.330 and time. 04:51.330 --> 04:53.100 So I just need the R right. 04:53.280 --> 04:53.970 I run this. 04:53.970 --> 05:01.650 This is going to print the r that is associated with the local date time and the R six, which is 6 05:01.650 --> 05:03.030 a.m. in the morning here. 05:04.310 --> 05:07.220 Now what I'm going to do, I need the minute. 05:09.560 --> 05:10.670 How do we do it? 05:11.060 --> 05:13.480 So there is a handy method called get minute. 05:13.490 --> 05:16.280 I'm going to use that method and print the result. 05:19.870 --> 05:20.330 There you go. 05:20.350 --> 05:22.450 It printed the minute as 615. 05:22.540 --> 05:28.780 We take a look at the current machines time, the machines, current time it is 615. 05:28.780 --> 05:30.850 So and we got the 15 out of it. 05:30.880 --> 05:33.670 Let's say I want the day. 05:35.300 --> 05:35.930 How do we do it? 05:35.960 --> 05:38.960 There is a method called Get day of the Month. 05:39.510 --> 05:44.930 We give this value going to print the day of the month. 05:45.440 --> 05:47.690 The day of the month is 17. 05:48.850 --> 05:54.520 So these are the different options that are available in order to get the values from the local datetime. 05:54.520 --> 05:57.220 And it also supports the width method. 05:57.280 --> 05:58.990 Let's explore a couple of those. 06:00.850 --> 06:02.080 Local date. 06:03.070 --> 06:04.360 So if we do with. 06:05.350 --> 06:07.840 That is the way of modifying. 06:07.960 --> 06:08.740 Let's cover this. 06:08.740 --> 06:13.840 When we actually modify the when we want to modify the local daytime instance, there is a get method 06:13.840 --> 06:15.750 that is the one which I wanted to cover. 06:15.760 --> 06:19.150 So if you do a get, it accepts a temporal field, right? 06:19.330 --> 06:23.650 So in here we can pass Chrono Field dot one the day of the month. 06:24.880 --> 06:25.660 There we go. 06:25.870 --> 06:29.350 And then this is going to give you the day of the month. 06:29.350 --> 06:35.110 But here, if you take a look at it, we are using another approach in order to get a parameter or in 06:35.110 --> 06:38.260 order to get an attribute from the local date time instance. 06:38.260 --> 06:39.760 I'm going to run this example. 06:41.120 --> 06:41.540 There you go. 06:41.570 --> 06:44.900 It gave the value as 17 because that is the day of the month. 06:45.020 --> 06:50.030 Now let's go ahead and check what are the different options of modifying the values. 06:51.010 --> 06:52.270 In local daytime. 06:53.140 --> 06:58.000 Let's give a simple code command in order to differentiate this from the getting getting the values 06:58.000 --> 06:59.260 from the local daytime. 07:00.280 --> 07:04.380 Modifying local daytime. 07:04.990 --> 07:07.170 So let's say I want to add hours to it. 07:07.180 --> 07:09.340 I want to increase the hours by two. 07:09.670 --> 07:10.540 How do we do it? 07:10.570 --> 07:16.180 So I'm going to use the same local daytime dot you can do. 07:16.180 --> 07:21.270 Plus it has both the days and hours methods supported as part of local daytime. 07:21.280 --> 07:24.550 So I'm going to use plus hours and increase the hours by two. 07:25.810 --> 07:26.890 Let's put this. 07:28.590 --> 07:30.210 Was wrong button. 07:30.490 --> 07:33.450 So in here, I'm going to print this in the console. 07:33.930 --> 07:35.190 Let's put this this out. 07:37.950 --> 07:43.210 And then in here, I'm going to use the plus hours to put the plus hours. 07:44.530 --> 07:46.700 And let's run this and check the result. 07:46.720 --> 07:51.760 Right now, the result will give you 8 a.m. as a result. 07:51.790 --> 07:57.620 If you take a look at the time, the time change from 6 to 8, the current time is six. 07:57.650 --> 08:03.430 It changed the time from 6 to 8 because we have added two hours to the current time. 08:03.700 --> 08:06.070 Now I want to subtract the days. 08:06.070 --> 08:07.060 How do we do it? 08:07.090 --> 08:12.220 There is a handy method, which is the minus which we have seen as part of the local date and local 08:12.220 --> 08:14.140 time tutorials. 08:14.140 --> 08:16.900 So I want to minus the days by two. 08:17.500 --> 08:21.360 So this is going to reduce the date by two. 08:21.370 --> 08:23.190 The current date is 17. 08:23.200 --> 08:26.650 This is going to change the date to 15. 08:26.980 --> 08:28.300 Let's run this and check. 08:30.480 --> 08:31.350 We take a look at it. 08:31.350 --> 08:34.470 The date changed from 17 to 15. 08:35.400 --> 08:36.030 There you go. 08:36.060 --> 08:37.740 Let's take a look at the width method. 08:40.100 --> 08:44.630 So what's going to be local date time dot width. 08:45.560 --> 08:47.240 Let's say you want to change the month. 08:47.970 --> 08:49.280 I want to change the month to 12. 08:49.430 --> 08:51.260 So the width method is handy. 08:51.260 --> 08:55.880 In order to modify the dates you can still use. 08:55.880 --> 08:57.530 Like what is a current month? 08:57.530 --> 08:58.700 The current month is seven. 08:58.700 --> 09:02.000 If you want to change that to 12, you will add a plus five. 09:02.240 --> 09:08.630 So with month, with month is going to change the local times month to 12. 09:10.970 --> 09:12.920 Then let's run this and check the result. 09:14.670 --> 09:15.360 Here we go. 09:15.390 --> 09:18.690 It changed a month from 5 to 12. 09:18.720 --> 09:24.400 So these are the different handy options which you can use in order to modify the local date and time. 09:24.420 --> 09:26.060 There are many more options available. 09:26.070 --> 09:31.860 I would highly recommend you guys to go ahead and explore it and raise any kind of question in the Q&A 09:31.860 --> 09:32.280 section. 09:32.280 --> 09:36.120 I would be able to answer you as soon as I can with this. 09:36.150 --> 09:37.810 We came to the end of this tutorial. 09:37.830 --> 09:38.970 Thank you for watching.
