1

00:00:00,300 --> 00:00:03,660

So as you can see here first I put that person's character.



2

00:00:03,810 --> 00:00:07,530

And then I specified the precision here thought free.



3

00:00:07,560 --> 00:00:10,700

This means that my value is going to accept the free decimal digits.



4

00:00:10,710 --> 00:00:11,350

OK.



5

00:00:12,170 --> 00:00:15,730

And then the type of My value is float.



6

00:00:15,880 --> 00:00:16,520

OK.



7

00:00:16,820 --> 00:00:25,000

So first I put the percent challenger here and then I specified My number of decimal digits.



8

00:00:25,340 --> 00:00:28,880

And then I specified the type of my value OK.



9

00:00:28,970 --> 00:00:31,270

And then I put a new line character here.



10

00:00:31,400 --> 00:00:35,490

And as you can see here here we need to specify our arguments.



11

00:00:35,510 --> 00:00:38,660

So now I can actually specify a floating point number.



12

00:00:38,660 --> 00:00:42,430

For example to point fifty six.



13

00:00:42,580 --> 00:00:43,210

OK.



14

00:00:43,460 --> 00:00:47,230

And then I need to put in a semi-colon at the end of my statement.



15

00:00:47,450 --> 00:00:54,110

And now if I want to output the value of this float string object to the console I just need to type



16

00:00:54,110 --> 00:01:00,830

in here systemd thought out that print to learn and then inside the prentices I just need to refer to



17

00:01:00,830 --> 00:01:03,290

the name of my object float.



18

00:01:03,710 --> 00:01:07,620

And then I need to put in a semi-colon at the end of my statement.



19

00:01:07,910 --> 00:01:12,800

And now if I get on my project as you can see it's going to actually output this value to the console



20

00:01:13,070 --> 00:01:16,510

a floating point number which free decimal digits.



21

00:01:16,640 --> 00:01:23,220

OK two point five six zero as you can see our number was two point fifty six.



22

00:01:23,330 --> 00:01:29,210

But because I specified that my value is going to accept Frida's free the single digits.



23

00:01:29,230 --> 00:01:31,640

It actually put a zero here.



24

00:01:31,840 --> 00:01:35,100

OK so now let me try to show you another example.



25

00:01:35,720 --> 00:01:41,230

So first of all let me actually comment out these lines of code here.



26

00:01:41,270 --> 00:01:48,800

So again it referred to the name of the String class as strange and the name of my object is floats



27

00:01:49,190 --> 00:01:51,270

as strange too.



28

00:01:51,620 --> 00:01:55,340

And then I need to put in an assignment operator here.



29

00:01:55,640 --> 00:02:01,540

And then again I refer to the name of the String class as three in that format.



30

00:02:01,580 --> 00:02:08,070

So first I need to specify the formatting instructions for my object here.



31

00:02:08,180 --> 00:02:11,080

As you can see it need to actually put a value of type A string.



32

00:02:11,090 --> 00:02:12,860

Ok a string format.



33

00:02:13,040 --> 00:02:16,660

OK so I just need to put in two double quotes here.



34

00:02:16,940 --> 00:02:23,310

And that inside the double quotes I can specify the formatting instructions so I can just type in here.



35

00:02:23,330 --> 00:02:27,240

A floating point number 10 decimal digits.



36

00:02:27,290 --> 00:02:29,220

And then I put in a call on here.



37

00:02:29,660 --> 00:02:32,500

And then again I put in the percent character here.



38

00:02:32,870 --> 00:02:36,310

Point 10 F. OK.



39

00:02:36,320 --> 00:02:39,180

And then I put in a new line character here.



40

00:02:39,290 --> 00:02:40,110

OK.



41

00:02:40,520 --> 00:02:47,350

And for the arguments I just need to put in a floating point number for example three point seventy



42

00:02:47,350 --> 00:02:51,350

eight and then I need to put in a semi-colon at the end of my statement.



43

00:02:51,350 --> 00:02:59,690

And now I want to output this value to the console so I just need to type in here a system that outs



44

00:03:00,050 --> 00:03:03,010

that princeling line and then inside the prentices.



45

00:03:03,050 --> 00:03:09,230

I just need to refer to the name of my float string to object and then I need to put in a semi-colon



46

00:03:09,290 --> 00:03:10,840

at the end of my statement.



47

00:03:10,850 --> 00:03:15,070

So now if I run my project as you can see it's going to output this value to the console.



48

00:03:15,260 --> 00:03:16,340

So as you can see here.



49

00:03:16,370 --> 00:03:19,930

So as you can see here it put ten decimal digits here.



50

00:03:19,940 --> 00:03:23,900

OK so now let me actually to show you another example.



51

00:03:23,900 --> 00:03:27,340

So first let me ask you to comment out these lines of code here.



52

00:03:27,350 --> 00:03:35,740

So here again I referred to the name of the string class as strange value OK.



53

00:03:36,050 --> 00:03:39,120

And then I put in an assignment operator here.



54

00:03:39,290 --> 00:03:44,650

And then again I refer to the name of this thing class that format.



55

00:03:45,230 --> 00:03:46,080

OK.



56

00:03:46,460 --> 00:03:50,960

So remember that this for my benefit is a classmate for the K because we are calling this an method



57

00:03:50,990 --> 00:03:52,450

on this string class.



58

00:03:52,460 --> 00:03:52,980

OK.



59

00:03:53,000 --> 00:03:59,090

So here as you can see we need to specify the formatting instructions of our object.



60

00:03:59,090 --> 00:04:07,670

So here I just need to put into double quotes and then I can just typing as I think colon and then I



61

00:04:07,670 --> 00:04:10,470

need to put in the person character here.



62

00:04:10,790 --> 00:04:15,570

And now I want to specify the type of the object that will be formatted in the output.



63

00:04:15,650 --> 00:04:16,430

OK.



64

00:04:16,520 --> 00:04:17,380

Percent.



65

00:04:17,600 --> 00:04:18,500

Yes.



66

00:04:18,500 --> 00:04:20,860

So the type of My object is a string.



67

00:04:20,870 --> 00:04:21,590

OK.



68

00:04:21,650 --> 00:04:26,610

And here for the arguments I need to actually putting a string object.



69

00:04:26,630 --> 00:04:30,070

So I just need to put into double quotes and inside double quotes.



70

00:04:30,110 --> 00:04:33,140

I can just put in for example high.



71

00:04:33,560 --> 00:04:36,620

And then I need to put in a semicolon at the end of my statement.



72

00:04:36,830 --> 00:04:40,750

And now I want to output the string value object to the console.



73

00:04:40,850 --> 00:04:41,360

OK.



74

00:04:41,490 --> 00:04:50,360

System that out that print line and then inside Apprentice's I can just refer to the name of the object



75

00:04:50,390 --> 00:04:55,850

a string value and then I need to put in a semicolon at the end of my statement.



76

00:04:56,040 --> 00:05:01,590

And now if I had on my project as you can see this value is now out to the console OK.



77

00:05:01,880 --> 00:05:09,130

So for example here I specified that the type of the object that is going to be formatted is a string.



78

00:05:09,180 --> 00:05:12,510

Ok so this is here means as I think.



79

00:05:12,680 --> 00:05:21,290

But if we actually change this to D which is used for integer numbers and as you can see here I specified



80

00:05:21,350 --> 00:05:24,250

that my object type is a string.



81

00:05:24,260 --> 00:05:24,680

OK.



82

00:05:24,680 --> 00:05:30,770

So as you can see here I specify that my object type is going to be integer.



83

00:05:30,800 --> 00:05:37,670

But here I put a strange value and if I get on my project now is it's going to actually show us an error



84

00:05:37,970 --> 00:05:40,290

exception in Fred Maine.



85

00:05:40,310 --> 00:05:41,490

This is a runtime error.



86

00:05:41,510 --> 00:05:42,170

OK.



87

00:05:42,260 --> 00:05:48,970

And this means that our codes have a problem and we need to fix our problems in order to fix this issue.



88

00:05:48,980 --> 00:05:50,080

So as you can see here.



89

00:05:50,240 --> 00:05:56,900

First of all we specified that the type of the object that is going to be formatted is of type integer.



90

00:05:57,050 --> 00:06:00,700

But here we put us through in value and this is rank.



91

00:06:00,800 --> 00:06:05,740

Even if you actually put an integer number for example number five.



92

00:06:06,010 --> 00:06:09,430

And now if I don't my project is going I should put this value to the cost.



93

00:06:09,490 --> 00:06:17,430

OK so now let me try to change this to S and here I put in the word high here.



94

00:06:17,500 --> 00:06:18,680

OK.



95

00:06:19,520 --> 00:06:20,020

OK.



96

00:06:20,090 --> 00:06:22,700

So now let me actually show you another example.



97

00:06:22,820 --> 00:06:29,670

So first let me actually comment out this line of code here and now I want to actually create another



98

00:06:29,930 --> 00:06:30,440

object.



99

00:06:30,440 --> 00:06:36,320

So first I need to refer to that name of the String class as the range and the name of my object is



100

00:06:36,500 --> 00:06:41,560

multiple string values.



101

00:06:41,870 --> 00:06:42,620

OK.



102

00:06:42,950 --> 00:06:47,160

And then I need to put in an assignment operator here.



103

00:06:47,450 --> 00:06:52,340

And then again I refer to the name of the String class that format.



104

00:06:52,340 --> 00:06:59,060

So first I need to specify the formatting instructions of my objects that is going to be output to the



105

00:06:59,060 --> 00:06:59,730

console.



106

00:06:59,870 --> 00:07:02,110

I put into double quotes and here.



107

00:07:02,300 --> 00:07:13,880

First of all I just type in a strange colon person s ok and I put a space here and then here I just



108

00:07:13,880 --> 00:07:19,570

type in integer colon percent D.



109

00:07:20,060 --> 00:07:22,510

And then again I put another space here.



110

00:07:22,610 --> 00:07:27,410

Float Colan percent character F..



111

00:07:27,730 --> 00:07:28,470

OK.



112

00:07:28,690 --> 00:07:34,980

So here as you can see we've got three different types for free different arguments.



113

00:07:35,000 --> 00:07:35,740

Ok so.



114

00:07:35,840 --> 00:07:41,420

So here we need to actually specify free different arguments for these three different types.



115

00:07:41,420 --> 00:07:41,780

OK.



116

00:07:41,810 --> 00:07:43,720

That we specified here.



117

00:07:43,790 --> 00:07:46,670

So here we need to actually put in our arguments.



118

00:07:46,670 --> 00:07:53,240

So for the first one for the first argument we need to actually putting in a strange value for example.



119

00:07:53,820 --> 00:08:00,500

Hello and for the second type we need to putting an integer number.



120

00:08:00,500 --> 00:08:09,290

For example fifty eight and for the first type we need to put in a floating point number.



121

00:08:09,290 --> 00:08:12,520

For example five point four.



122

00:08:12,740 --> 00:08:13,670

OK.



123

00:08:13,670 --> 00:08:16,520

And then we need to put in a semi-colon at the end of my statement.



124

00:08:16,770 --> 00:08:17,400

OK.



125

00:08:17,630 --> 00:08:20,880

And now I want to output this value to the console OK.



126

00:08:20,900 --> 00:08:26,510

So here I just need to typing system that out that princeling.



127

00:08:26,930 --> 00:08:31,490

And then inside the prentices I can just revert to the name of my object multiple



128

00:08:34,470 --> 00:08:38,310

values and that I need to put in a semicolon at the end of my statement.



129

00:08:38,610 --> 00:08:43,710

And now if I had on my project as you can see it's going to actually output these values to the console



130

00:08:43,790 --> 00:08:44,270

S3.



131

00:08:44,310 --> 00:08:47,850

Hello As you can see here estrange.



132

00:08:47,870 --> 00:08:48,790

Hello.



133

00:08:49,240 --> 00:08:54,910

Integer fifty eight and float five point as you can see here.



134

00:08:54,950 --> 00:09:04,970

It actually puts 1 2 3 4 5 6 decimal digits 6 decimal digits for our floating point number as you can



135

00:09:04,970 --> 00:09:09,050

see we didn't specify the decimal digits for our floating point numbers.



136

00:09:09,110 --> 00:09:13,470

So it actually put 6 decimal digits for our floating point number.



137

00:09:13,490 --> 00:09:14,060

OK.



138

00:09:14,180 --> 00:09:17,840

And now let me actually show you another example.



139

00:09:17,840 --> 00:09:25,490

So now I just need to refer to the name of the string class a string and the name of my object is for



140

00:09:25,490 --> 00:09:30,580

example s t r value 1.



141

00:09:30,830 --> 00:09:38,540

And then I need to put in a semicolon here and then I need to put in an assignment operator here and



142

00:09:38,540 --> 00:09:42,790

then again I refer to the name of the String class that format.



143

00:09:43,340 --> 00:09:47,830

And here I need to specify the formatting instructions for my object.



144

00:09:47,840 --> 00:09:53,860

So I just need to put in here to double quotes and inside the double codes I can specify the formatting



145

00:09:53,870 --> 00:09:54,730

instructions.
