1 00:00:00,180 --> 00:00:04,450 So that type of my valuable is float OK. 2 00:00:04,620 --> 00:00:09,330 And the name of my value is Celsius OK. 3 00:00:09,480 --> 00:00:12,690 And then I assign a value to my variable here. 4 00:00:12,780 --> 00:00:13,560 OK. 5 00:00:13,950 --> 00:00:16,320 For example 86. 6 00:00:16,470 --> 00:00:17,000 OK. 7 00:00:17,160 --> 00:00:20,940 And then at the end of my statement I need to put in a semi-colon OK. 8 00:00:21,060 --> 00:00:25,500 So now I want to output the value of this variable to the console. 9 00:00:25,490 --> 00:00:25,950 OK. 10 00:00:27,600 --> 00:00:33,360 System that out that prevents land and then inside the prentices I just need to refer to the name of 11 00:00:33,360 --> 00:00:34,480 my variable. 12 00:00:34,790 --> 00:00:35,190 OK. 13 00:00:35,190 --> 00:00:38,580 And then at the end of my statement I need to put in a semi-colon. 14 00:00:38,580 --> 00:00:43,500 So now if I run my project as you can see it outputs this value to the console. 15 00:00:43,530 --> 00:00:51,710 OK so now the first step is that we need to multiply the Celsius value by night. 16 00:00:51,750 --> 00:00:52,370 OK. 17 00:00:52,560 --> 00:00:56,430 So again I just need to refer to the name of my variable here. 18 00:00:56,760 --> 00:00:58,270 Celsius Okay. 19 00:00:58,650 --> 00:01:04,550 And then I put in an assignment operator here because I want to assign a value to my value. 20 00:01:04,560 --> 00:01:05,030 OK. 21 00:01:05,040 --> 00:01:10,680 And then I put in an assignment operator here and then I want to assign a value to my value. 22 00:01:10,920 --> 00:01:14,960 So again I refer to the name of my variable in order to read it it's. 23 00:01:15,030 --> 00:01:23,110 OK Celsius and then I multiply this value OK by nine. 24 00:01:23,520 --> 00:01:26,310 And then at the end of my statement I need to put in a semi-colon. 25 00:01:26,310 --> 00:01:27,110 OK. 26 00:01:27,750 --> 00:01:35,910 So now if I output the value of this valuable to the console Let's see what happens system that I got 27 00:01:36,220 --> 00:01:42,140 that slam inside the Prentice's referred to the name of your variable. 28 00:01:43,290 --> 00:01:46,710 And then at the end of your statement you need to put in a semi-colon. 29 00:01:46,710 --> 00:01:47,360 OK. 30 00:01:47,820 --> 00:01:52,680 So if I used on my project as you can see it outputs this value for the cost. 31 00:01:52,680 --> 00:01:57,550 OK this is the last value of this Celsius variable here. 32 00:01:57,690 --> 00:01:58,160 OK. 33 00:01:58,260 --> 00:02:03,050 And this value is the old value of this Celsius variable here. 34 00:02:03,060 --> 00:02:03,590 OK. 35 00:02:03,760 --> 00:02:12,700 We created this Celsius variable in line between the free and we decided to output the value of this 36 00:02:12,880 --> 00:02:20,830 variable to the console and we decided to output the value of this variable to the console in line 24. 37 00:02:20,890 --> 00:02:21,600 Okay. 38 00:02:21,910 --> 00:02:27,200 And as you can see here in the console it outputs this value to the console. 39 00:02:27,350 --> 00:02:27,710 Okay. 40 00:02:27,730 --> 00:02:33,270 Because in this line we are actually outputting the value of this value back to the console. 41 00:02:33,460 --> 00:02:33,930 Okay. 42 00:02:34,030 --> 00:02:41,280 And when and when and when this line is executed it it's going to out food this number with the console 43 00:02:41,470 --> 00:02:49,040 but in line 26 as you can see we changed the value of this variable to another value. 44 00:02:49,140 --> 00:02:49,610 Okay. 45 00:02:49,640 --> 00:02:56,230 The first with the name of the variable and then we use the assignment operator in order to assign a 46 00:02:56,230 --> 00:02:57,590 value to my value. 47 00:02:57,670 --> 00:02:58,230 Okay. 48 00:02:58,540 --> 00:03:04,880 And on the right hand side of the operator I multiplied the value of this variable by nine. 49 00:03:04,970 --> 00:03:05,450 OK. 50 00:03:05,560 --> 00:03:14,110 And then I assigned the result of this operation to the Celsius variable and in line 27 I decided to 51 00:03:14,110 --> 00:03:17,130 output the value of this variable to the console. 52 00:03:17,330 --> 00:03:17,820 OK. 53 00:03:17,890 --> 00:03:22,990 So now as you can see this is the last value of these Celsius variable. 54 00:03:23,040 --> 00:03:23,600 Okay. 55 00:03:23,680 --> 00:03:30,040 So this is a very important point that you should consider about about assigning values to variables. 56 00:03:30,040 --> 00:03:33,890 OK so now we need to actually divide the result by 5. 57 00:03:33,970 --> 00:03:34,580 OK. 58 00:03:34,900 --> 00:03:43,690 So here again I refer to the name of my variable and then I use the assignment operator here because 59 00:03:43,720 --> 00:03:46,670 I want to assign another value to this variable. 60 00:03:46,780 --> 00:03:50,910 I want to divide the value of this variable by 5. 61 00:03:51,130 --> 00:03:51,740 OK. 62 00:03:52,010 --> 00:03:55,620 You want to divide this number by 5. 63 00:03:55,660 --> 00:03:58,780 So I just need to again refer to the name of my variable. 64 00:03:59,470 --> 00:04:03,890 And then use that division operator here and then put the number five here. 65 00:04:03,940 --> 00:04:04,470 OK. 66 00:04:04,630 --> 00:04:07,820 And then at the end of my statement I need to put in a semi-colon. 67 00:04:08,050 --> 00:04:15,170 So here again I want to output the value of this variable to the console system that I want that print 68 00:04:15,170 --> 00:04:15,730 to Len 69 00:04:19,840 --> 00:04:25,100 and then inside Apprentice's I just need to refer to the name of my variable Celsius. 70 00:04:25,300 --> 00:04:28,540 And then at the end of my statement I need to put in a semicolon. 71 00:04:28,540 --> 00:04:29,090 OK. 72 00:04:29,530 --> 00:04:36,540 So now if I run my project as you can see it's going to output this value to the console. 73 00:04:37,210 --> 00:04:41,260 This value is the result of this operation here. 74 00:04:41,650 --> 00:04:48,740 OK that be assigned to Celsius variable and in this line of code are in line. 75 00:04:48,770 --> 00:04:52,110 Firstly we decided to output this value to the console. 76 00:04:52,360 --> 00:04:54,810 So as you can see here this is that value. 77 00:04:54,950 --> 00:04:59,860 OK this is the last value that we assigned to the Celsius variable. 78 00:05:00,120 --> 00:05:00,730 Okay. 79 00:05:00,970 --> 00:05:04,810 And finally we need to actually be at fifty two values to this number. 80 00:05:04,880 --> 00:05:09,190 Okay this is the last value of this Celsius variable. 81 00:05:09,460 --> 00:05:11,900 So just like in here Celsius. 82 00:05:12,310 --> 00:05:13,010 Okay. 83 00:05:13,270 --> 00:05:16,250 And again I use the assignment operator. 84 00:05:16,720 --> 00:05:20,490 And then I want to assign another value to this variable. 85 00:05:20,530 --> 00:05:21,010 OK. 86 00:05:21,130 --> 00:05:29,110 So here I just need to refer to the name of a variable and then add 32 values to the value of my. 87 00:05:29,190 --> 00:05:29,870 OK. 88 00:05:30,130 --> 00:05:33,490 And at the end of my statement I need to put in a semi-colon. 89 00:05:33,610 --> 00:05:39,560 So now if you want to output the value of this variable to the console I just need to type in here system 90 00:05:39,710 --> 00:05:41,390 out of that plane to land. 91 00:05:41,980 --> 00:05:46,190 And then inside the apprentice's I just need to refer to the name of my body. 92 00:05:46,240 --> 00:05:47,300 OK. 93 00:05:47,950 --> 00:05:51,840 And then at the end of my statement I need to put in a semi-colon OK. 94 00:05:52,150 --> 00:05:59,010 So now if I actually run my project as you can see it's going to output this value to the console. 95 00:05:59,020 --> 00:05:59,750 OK. 96 00:06:00,040 --> 00:06:05,300 So if we successfully converted this Celsius value into farenheit. 97 00:06:05,320 --> 00:06:05,930 Okay. 98 00:06:06,150 --> 00:06:08,500 And this is our value. 99 00:06:08,560 --> 00:06:15,610 So here again I want to actually concatenate the value of this variable with another text. 100 00:06:15,610 --> 00:06:18,390 So I just use the plus operator here. 101 00:06:18,670 --> 00:06:21,320 And then I put two double quotes here. 102 00:06:21,430 --> 00:06:24,900 And then inside the double codes I just need to put in my text. 103 00:06:24,940 --> 00:06:27,680 So here I use the space here. 104 00:06:27,880 --> 00:06:31,630 And then I just need to type in degrees 105 00:06:34,920 --> 00:06:35,640 Fahrenheit 106 00:06:38,360 --> 00:06:39,060 OK. 107 00:06:39,530 --> 00:06:46,480 So now if I run my project again as you can see it's going to output this value to the con.. 108 00:06:46,490 --> 00:06:47,100 OK. 109 00:06:47,120 --> 00:06:50,970 And this is the value that we converted from Celsius to Fahrenheit. 110 00:06:51,320 --> 00:06:55,450 And this is the text that we pulled after this variable here. 111 00:06:55,490 --> 00:06:56,020 OK. 112 00:06:56,150 --> 00:07:01,520 So now I want to actually explain more about other aspects of Java programming. 113 00:07:01,570 --> 00:07:07,720 Ok so now let me actually comment out these lines of code here because I don't want to execute them. 114 00:07:07,850 --> 00:07:14,280 OK so as you can see I use the multiline comment here in order to comment out all these lines here. 115 00:07:14,330 --> 00:07:22,490 OK so the first point that I want to talk about is that you can combine assignment statements in this 116 00:07:22,880 --> 00:07:25,340 unusual way that I'm going to show you. 117 00:07:25,530 --> 00:07:29,570 OK so first I'm going to declare some variables here. 118 00:07:29,690 --> 00:07:36,980 So in the data type of my variable is 8 and then the name of my variable is for example a the data type 119 00:07:36,980 --> 00:07:37,900 of my second value. 120 00:07:37,900 --> 00:07:39,530 But is it. 121 00:07:40,100 --> 00:07:43,050 And the name of my second value and is B. 122 00:07:43,310 --> 00:07:43,980 OK. 123 00:07:44,300 --> 00:07:52,740 And I want to declare another variable and see and hear the last value about that I want to create here. 124 00:07:52,760 --> 00:07:55,930 I want to actually assign a value to my value it. 125 00:07:55,940 --> 00:07:57,920 OK so ain't it. 126 00:07:57,980 --> 00:08:01,740 And then I assign for example Number five to my variable here. 127 00:08:01,810 --> 00:08:02,740 OK. 128 00:08:03,710 --> 00:08:10,540 So now I want to show you that you can combine assignment statements in this unusual way. 129 00:08:10,700 --> 00:08:20,570 So a is equal to B is equal to C is required to set and then at the end of my statement I need to put 130 00:08:20,570 --> 00:08:21,660 in a semicolon. 131 00:08:21,950 --> 00:08:24,280 So now let's see what happens here. 132 00:08:24,380 --> 00:08:34,070 System that out that print learn and then inside the parenthesis I just need to refer to the name of 133 00:08:34,070 --> 00:08:35,240 my valuables here. 134 00:08:35,300 --> 00:08:35,950 OK. 135 00:08:36,140 --> 00:08:39,800 So I just typed in here a 136 00:08:43,140 --> 00:08:49,820 and then I use the plus operator in order to concatenate this text with my a variable here. 137 00:08:50,130 --> 00:08:51,180 OK. 138 00:08:51,930 --> 00:09:01,320 And again I use the plus operator and then inside the double codes I type in B and then I use this space 139 00:09:01,320 --> 00:09:01,670 here. 140 00:09:01,680 --> 00:09:04,560 And then I concatenate this text. 141 00:09:04,560 --> 00:09:06,690 It might be valuable. 142 00:09:06,870 --> 00:09:09,600 Again I use the plus operator here. 143 00:09:09,660 --> 00:09:17,040 And then inside the double quotes I just type in here see and again I use the plus operator in order 144 00:09:17,040 --> 00:09:27,050 to concatenate this text fit my C variable and then again I use the plus operator here concatenate with 145 00:09:27,150 --> 00:09:29,750 another text here said. 146 00:09:30,360 --> 00:09:35,930 And then I use the plus operator in order to concatenate this text with does that. 147 00:09:36,030 --> 00:09:36,880 OK. 148 00:09:37,320 --> 00:09:40,230 And then at the end of my statement I need to put in a semicolon. 149 00:09:40,230 --> 00:09:46,420 So now let me actually put his space here and there are space here and another space here. 150 00:09:46,450 --> 00:09:50,290 OK so now if I run my project let's see what happens.
