What a video, simple, clear, outstanding. Golden Marks for one who created this originally, the narrations, the design, the words. Great Work.

@RiyaTomar-jd3mw 4 года назад

Very well explained from the very beginning to a person like me who is just a newbie to coding and stuff. JAVA is the first language I'll be studying or probably doing programming with. Thank You!!

OMG!! , this is pure gold. It just cannot get clearer and more concise than this in 6 minutes. It just says it all but at high level so so that you can then go ahead and search for more info on whatever section your are interested in. I will keep this as a reference for whenever I want to give an example of a good clear explanation.

@bmgag19 8 лет назад

still very confused. writing a compiler for each platform is expensive? then why is writing an interpreter in the jvm for each platform not expensive? how is this different?

@nicachoii 6 лет назад

Because the jvm/interpreter is compatible for all of the platform, so you will only need one. thus, it is inexpensive compare to compiler where you need different one for each platform.

Println is literally short for "print line", specifically to imply it will append a trailing newline character. Great explanation of compilation and motivation for learning Java otherwise!

@RiyaTomar-jd3mw 4 года назад

3:14 if all that assembly code was converted to that single line C language code , then why using a compiler to convert that C language code again to assembly language and then to machine code , then what's the use of converting all that stuff to that C language code if it was required to convert it again to assembly language.

@tahaait7236 4 года назад

First, there is what we call high level programming language. High level means that the language is very close to human language, so it is easy to understand and interpret for a human being. Moreover, it's very helpful in code optimization, so that 1 line of code in high level is equivalent to multiple lines in assembly. So if i ask u, what would you choose when you want to code an application that contains lots of code lines? you'll chose high level, because it's easy for u. (C and Java are high-level) Second, we never convert code in assembly to C language. This will be with no sense, since assembly language is the one that's close to machine code. Normally, whether we write code in assembly which will be converted to machine code . Or rather instead we write code in C (or any other high-level language) then it'll be compiled to assembly then converted to machine code. And guess what for each plateform we need a convenient compiler. But with JVM the java compiler compiles code to bytecode then the later is interpreted to the right machine code depending on the plateform we're working on.

@iampyre2016 6 лет назад

a computer isn't an electronic device, it CAN be an electronic device. There were computers way before man conceived of electronics; it's simply something that makes calculations. An electronic design and architecture of a computer is the best thing man has come up with to make and process calculations.

@griffink5554 5 лет назад

I think it was implied he was talking about modern computers, I think if your learning java in college your at least at the point when you know what a computer is.

@NarcoticRebel97 10 лет назад

very good tutorial but you made a mistake. it is System.out.println (PRINTLN) not PRINT in. I use the most current compiler and i use eclipse and it is an L not an I only that the i uppercase looks like the L lower case, here they are side by side Il... see, it is println, all lower case

@NarcoticRebel97 10 лет назад

println stands for Print Line not print in

@guru99com 10 лет назад

You are correct. Wondering how this mistake seeped through

@NarcoticRebel97 10 лет назад

***** I was actually expecting you to deny it or argue, you are very humble, thats a rare trait nowadays... btw your java tutorials seem to be missing parts, is this on purpose or am i just no finding the other parts?

The missing parts are text tutorials and can be found on our website guru99.com

@shantanukulkarni8883 7 лет назад

if you don't know any definitions, then ur not dumb, 'cause we all don't know.. But if you don't know basic stuff like input- output, then u should go watch an explanation on that, lol.

@neencreates 7 лет назад

oh thanks, ill try

@shantanukulkarni8883 7 лет назад

yesss, Also, I don't think that you will learn entire language if you are lazy.. Because I am lazy and so I can't concentrate on anything.... So I will tell you one thing- Don't think that you are going to make a game or something if you learn Java.. Because it needs practice and patience in writing code.. So yeaaahhhh.. that's it.

@neencreates 7 лет назад

Thanks a bunch, my true intention was not making a game, i want to learn everything so i can do haxs :P

@Zyphyr420 5 лет назад

i think it means you are an idiot, and this stuff is very basic and beginner level. just do research and read books about it and you will learn, after all life is an experience and its up to you to decide if its a good one or not.

System.out.println() --> PRINTLN (not IN) LN stands for line, which means print line. Notice that println() adds a line break ( ) at the end of the line while print() does not.

@iampyre2016 6 лет назад

Wintel??? Never heard that term, I thought that was the PC platform.

@BappuDebNath 8 лет назад

@techsupport1294 9 лет назад

"Store 1 at memory location say A" "This VM runs in the RAM" Classic java, wasting as much ram as possible. In assembly it'd only be: add r0, #1, #2 (no ram) The coding in here is terrible e.g. printf(1+2) should be printf("%i ", 1+2); "Compilers come expensive" except for those all those free ones... system.out.printin(1+2) saved as .java. :|
