00:00:00,730 --> 00:00:08,000

Hello and welcome to a new section in this new section, we are going to take a look at analyzing Java.



2

00:00:08,740 --> 00:00:20,050

We start off by looking at how to disassemble Java by code, how Java program runs in this diagram here



3

00:00:20,320 --> 00:00:25,390

on the left, you see the development tools, for example, IDs on.



4

00:00:25,900 --> 00:00:29,110

These are tools used to create Java programs.



5

00:00:29,800 --> 00:00:33,280

And on the right is a Java runtime environment.



6

00:00:33,970 --> 00:00:38,020

And your environment consists of the Java, which machine?



7

00:00:38,800 --> 00:00:46,150

And then we have to force Java class library and Java Archive files, also known as G.



8

00:00:46,180 --> 00:00:51,580

He are the Java Class Library and Java Archive.



9

00:00:51,580 --> 00:00:59,290

G.R. comes from the development tools, the development to the source code and the Java Class Library,



10

00:00:59,590 --> 00:01:01,240

all the Java archive.



11

00:01:02,620 --> 00:01:12,640

So the Java class is actually the vehicle itself and the Java Archive Jaara is a collection of classes



12

00:01:12,940 --> 00:01:14,470

compressed into a high.



13

00:01:15,760 --> 00:01:22,630

And then the issue is, how are we to machine the giant washing machine is over Java runtime and this



14

00:01:22,630 --> 00:01:29,830

is the interpreter which converts to Java class and Java Akki into machine.



15

00:01:29,830 --> 00:01:31,660

It is good for execution.



16

00:01:33,060 --> 00:01:40,880

Now, this is not a diagram showing you in more detail how the Java program is created and runs now



17

00:01:40,890 --> 00:01:47,920

know that the Java with Machine JVM is also known as the GRV Java runtime environment.



18

00:01:48,450 --> 00:01:50,490

And it points to the interpreter.



19

00:01:50,910 --> 00:01:58,700

Now, this interpreter is different for every machine you have, Java, which is a machine for Mac,



20

00:01:58,720 --> 00:02:00,750

Linux and Windows.



21

00:02:01,560 --> 00:02:03,370

However, the bikeway is the same.



22

00:02:04,130 --> 00:02:10,650

If I could use created from the source code to Java compiler.



23

00:02:11,820 --> 00:02:20,040

And that's why we say when the Java Paykel is created, you can run on any machine just like in that



24

00:02:20,040 --> 00:02:27,420

framework, because then Ambika is the same, but it is the interpreter in the person code for that



25

00:02:27,420 --> 00:02:29,190

particular machine to execute on.



26

00:02:29,700 --> 00:02:34,140

And the interpretation is done by the Java runtime.



27

00:02:35,080 --> 00:02:43,590

Also known as Gitti Compiler, Chessington Compiler, just like in the dot net framework, this example



28

00:02:43,860 --> 00:02:45,060

of the Buycott.



29

00:02:45,950 --> 00:02:53,290

In what he looks like on the right hand side of this diagram is a sample of her Sasko Gervasio school,



30

00:02:53,870 --> 00:03:01,190

there is a public class called Demo one, and inside there is a method called public static void main,



31

00:03:01,190 --> 00:03:07,190

which is the main method for all of our classes, and three for four instructions.



32

00:03:07,190 --> 00:03:15,910

Here we have a variable A which is assigning zero integer be assigned to indigency assigned three.



33

00:03:16,340 --> 00:03:25,700

And this one is evaluating the value in integer B, multiplying integer C and assigned to variable here.



34

00:03:26,240 --> 00:03:33,560

And here is where you print it up using the static method called Greenline, which comes from the system



35

00:03:33,560 --> 00:03:41,570

that our class and this on the left is the vehicle that represents the source code on the right.



36

00:03:42,290 --> 00:03:45,980

And you can see from here and this is what your bike looks like.



37

00:03:46,880 --> 00:03:51,980

And this one, two first two lines represent this line here.



38

00:03:51,980 --> 00:03:59,600

Integer is Hassane zero and the next two line here represents integer be assigned to and these two lines



39

00:03:59,600 --> 00:04:07,910

down here representing the U.S. sine three and then these lines here, six, seven, eight, nine represents



40

00:04:08,150 --> 00:04:14,930

this line is the same be multiplied by C and then down here get static.



41

00:04:15,200 --> 00:04:22,100

I don't want an equal which represents this line system up green line A so this is what the bank looks



42

00:04:22,100 --> 00:04:23,990

like Java does.



43

00:04:24,440 --> 00:04:29,670

This has all the tools you are going to be looking at first is Java.



44

00:04:29,690 --> 00:04:33,950

AP Jarobi is part of the Java development kit.



45

00:04:34,370 --> 00:04:35,390

It is a bytecode.



46

00:04:35,540 --> 00:04:36,410

This is semmler.



47

00:04:36,920 --> 00:04:45,750

It can convert binary back to back on the Java Sea, also part of the JDK in the Java development kit.



48

00:04:46,370 --> 00:04:48,440

He can combine Java into bytecode.



49

00:04:50,070 --> 00:04:57,810

And we also have another group of tools called Java Compilers, which can convert back straight back



50

00:04:57,810 --> 00:04:58,350

to Java.



51

00:04:59,400 --> 00:05:08,540

So the difference between Java being Java, the compiler is Dabi can only convert their binary to bind



52

00:05:08,950 --> 00:05:09,720

by code.



53

00:05:09,900 --> 00:05:12,840

That process is called disassembling Java.



54

00:05:12,840 --> 00:05:18,360

The compiler, on the other hand, can convert that back all the way back to Java source code.



55

00:05:18,840 --> 00:05:22,200

And that process is called decompiled Java.



56

00:05:22,200 --> 00:05:34,200

So this is basically Java and Java extension, for example, hello, Java, some Java Fuso and the extension



57

00:05:34,410 --> 00:05:36,960

class, for example, haloed class.



58

00:05:37,410 --> 00:05:43,170

And we are seeing this now, Hanada classes in Java by code, which has been Campath from the source



59

00:05:43,170 --> 00:05:43,440

code.



60

00:05:44,310 --> 00:05:51,900

And then we also had an distention where, for example, you have Farleigh hello at Dunya.



61

00:05:52,260 --> 00:06:02,000

And this Danja path, as I mentioned, is kind of a collection of classes, the internal extension Farzat,



62

00:06:02,010 --> 00:06:04,530

aka files containing multiple class we need.



63

00:06:05,250 --> 00:06:10,710

And now we are going to do a Latin demonstration of this assembling a Bikel.



64

00:06:11,160 --> 00:06:14,260

So go ahead and download the project.



65

00:06:14,260 --> 00:06:20,150

The Z and password to unzip is cracking lessons that come in.



66

00:06:20,160 --> 00:06:27,120

Unless we do, we are going to do that particular demo using this file, that peduncle.



67

00:06:27,450 --> 00:06:29,180

So I'll see you in the next lesson.



68

00:06:29,430 --> 00:06:30,510

Thank you for watching.
