Professor Mehran is a very dedicated and great teacher I wished I had him as a teacher.Some teacher may be knows the material but do not have the way to presented in a simple way................................Thanks for Stanford and Prof. Mehran
Get the book. It's called "The Art and Science of Java" by Eric Roberts. It's expensive, but there's always another way to get it if you're clever. Skim the chapters before watching the lecture so you'll have at least some clue as to what is going on, and then go back over the chapter after the lecture. Use a highlighter. Take notes. I'm following a strict MWF schedule to keep myself plowing through this course, it can be done, it just takes dedication.
Diversity, competition, brainstorming. We do live in a society... and beside that as an individual you can deepen what you learned in a group and then come back and share. And that's how evolution works. This is my theory.
So far, this course has been great. I wish he hadn't rushed the while loop description at 45:00. The loop would terminate when x==1, x would never be 0.
1 is not greater than 1, therefore the loop would terminate when X ==1. The case when X == 1, the loop never executes, therefore 1/2 never happens. The sequence of X values would be 15 (initial condition), 15/2 -> 7, 7/3 -> 3, 3/2 -> 1 (loop termination).
mgwilson271 He never says that the iteration executes while x was equal to one. He asked the students what 1 divided by 2 was and then said it does not run "which is not greater than 1 and we're done". If the reason it prints 1 is what confuses you then well lets break it down a bit further: condition, 15/2==7, prints 7 => condition, 7/2==3, prints 3 => condition, 3/2==1, prints 1 => condition, terminate.
weyderwarr Yes, I understood why "1" was printed. From the section in question: "So first time X has 15." "15's greater than 1." "We divide by 2." "We do integer division, so we get 7." "We write that out and go back up there." "7 is greater than 1. "We get 3." "We do it again, we get 1." "We do 1 divide equal 2 we get...... 0 which is not greater than 1, so we're done."
Cascading ifs and switch statements can easily break the 15-lines-per-method rule. Should I forget the rule in those cases? How could I enforce the rule?
I have a huge smile on my face. I had a cool little robot called Karel in my mind over the new year break. Yet another huge inspiration from Stanford University. I feel compelled to start a blog to share all my favourites as a thank you. Just searched the domain. It's available. I will post the link(s) soon.
I lost my interest in programming due to crappy teaching in my college and a tuition ... prof mehran seems to bring that interest back.. Thanks for the lectures @ stanford. :D
It's not about watching. Its about understanding. Your point of view is really funny. Its like: "If I watch this more than anyone else, I will be cool!!" It's like teenage wannabe programmer kids who use buckys tutorials to "learn" programming.
45:21 - Do you even get to 1/=2? Is 1 greater than 1? In the for loop he said "5 is not strictly less than 5", so is 1 not strictly greater than 1? Why would it be different in a while loop?
He got it wrong, he most likely should have: while(x >= 1) { x/= 2; (Or x = x/2) println(x); } That would have worked as 1 is greater than OR equal to 1. 1 is NOT greater than 1. So yes, you're correct.
It's better practice to cast something even as simple as real division. Later on when you start working with more complex ideas, type-casting can becoming really useful. Which is why you should get comfortable with them early on.
I made it check if there was a beeper present when he hit the wall, if there wasn't, it would be even, if there was, it would be uneven. From there I branched the program into two algorithm, one for even rows, on for uneven rows.
39:55 not really a problem but what if I did not choose a variable between 0-6? would it still bring me to default. In that case what could I have done to prevent it?
Yeah, anything that wasn't 0 or 6 would go to the default case. The default case is there as a catch-all to catch basically "anything else". The only real way to prevent going to the default case would be to have a case set up for whatever that choice is. You could enclose it in a _while_ loop that runs until a valid option has been chosen [e.g. while ( day != 0 || 6 ) { _prompt_ _and_ _switch_ }]. Then you could have the default case tell the user that their choice is invalid, and when it exits the _while_ loop would run the choice again.
21:50 - even SEVENTY_TWO is better than bare 72. Once you realize it means pixel per inch, you can safely rename SEVENTY_TWO to DISPLAY_PPI or something. But globally replacing 72 to, say, 120 for higher DPI would not be safe at all.
I don't quite understand with the program on 42:00 why it ends up starting with 0. The command seems to say "this is 0, I'll add 1, then I'll print". Why does it print the original i value instead of the after the change? Is there a quick way to have it change then print?
for (INIT; CONDITION; STEP) STATEMENT INIT happens once, before anything. The CONDITION is tested. If the CONDITION is true, then the STATEMENT is run. *AFTER* the STATEMENT is run, the STEP is executed. Even though the STEP is written above the STATEMENT, the STEP section of the `for loop` is only done after the whole loop has run. Hope that helps.
you may declare a variable of a higher scope, let be (x): int x = 0; then, add this statement in side the (for) block: x += i; it would be available after (for) block because it's of a higher scope!
Having a little trouble. I'm trying to do the assignments associated with this lesson (the pyramid one at the moment). I can do the assignment but to do so I feel like I have to abandon the "top-down" programming lesson taught earlier as I can't make a variable carry from one method to another. Advice?
I realise I'm a bit late here but as I understand it, as long as you declare the variable in the parent class of all the methods or classes you'd like the variable to have access to, they will inherit them and therefore have access to them: giving the variable a wide scope.
@xajin24 you need to download the acm package and import it to Eclipse so you can use it with this Course. Took me a while to figure it out, but if you need assistance, shoot me a message.
In the while loop example at the very end he says "1 divide equals 2 is 0, so we're done". However, the program would never do that, because as soon as we print 1 in the final step the condition in the while loop is no longer true (i.e., 1 is not greater than 1) so the body never executes.
Nah it works, just tested it. It will print the one from the 3 / 2 calculation, then go back to the while statement and since the x value is 1 it will end there.
@@plaidchuck Yes, it will end because 1 is not less than 1. It will never do the operation 1/2 to get 0. So "we're done" not because 1/2 is 0, but because 1 is not less than 1.
is there a big difference between the pdf version of "the art and sience of java" book and the full original version? Will i be able to complete the course and understand all the details with the pdf preliminary draft of the book, or will i miss alot of detail if i don't read the final example of the book?
Does anyone have access to the ORIGINAL course materials? Lecture code & slides, HW prompts, etc. The link directs to the current version of the class, which is different.
Hey, the for loop looks just like it does in C, cool. Python reminds me more of bash than C or Java. It's interesting to see the similarities and differences in syntax as well as general operation of these programming languages. I live near Mexico and I can't learn Spanish for the life of me, programming seems like a second nature, as if I had been thinking this way but didn't know how similar it was to programming. An old friend of mind who studied C++ in 8th grade said I was very "objective".
This isn't about disabled people or people that TOO LAZY TO TAKE A SELF DEFENSE CLASS, it is always better to learn in a group than as an individual. This is about the people that want to learn but LACK the means.
I like the lectures and have downloaded the entire series with firefox youtube download plugin So in case I'm not online I've uploaded the mp4s to my ipod touch and onto a Flash drive for rewatching, also in case they ever get taken off youtube.

Is readDouble(); a standard part of java? Or do i need to import something first? In my current classes we would first import java.util.Scanner; then use Scanner inp = new Scanner(System.in); System.out.print("enter double: "); double Variable = inp.nextDouble(); I have tried to use this before but it wont work, i'm just getting errors? I am using the newest version of eclipse. If it is possible to do without using import, can someone show me an example of code that will work in eclipse? Please include the code that will make it print to the console, like System.out.println(); would. if not what do I need to import first? It would save me writing a small bit of code, but I am more interested in why it is not working for me. Thanks in advance, any information will be appreciated.
+David Rodrigues i have tried and it works, but if you type in a double number like 2.3 it doesnt and it gives you "Exception in thread "main" java.util.InputMismatchException" i dont know why.
I don't have it anymore because I uninstalled Karel due to not using it anymore. They start using only simple java programs in assignment 2, but I did blog my solutions to Assignment 2 on my blog. Also you can find several solutions online just do a google search for checkerboard karel solution
ReadInt is reading what the user is inputting. You cannot print to the screen in a request for input. println("Day of the week int: "); readlnt(); I have not watched lecture 6 yet so I don't know exactly how the readInt is set up. In C, you have something known as scanf, which would kind of be C's version of readInt. To use scanf on an integer, you would simply scanf("%i", variable); The stuff within quotes cannot contain anything besides % followed by a type specifier (i or d for integer). With that in mind, I would assume you cannot put text that you want printed to the screen inside a readInt statement, as it is asking the user for input, not giving the user output.
I'm just wondering, what algorithm did you use for problem 3 from assignment 1 [CheckerboardKarel]? I only got it to work with the even-numbered rows world. If you know how, can you message me (via UA-cam)? Thanks.
What he says at 12:20 is not actually true. It actually won't cast the double automatically to an int because of a possible loss of precision. That line of code won't actually compile because it's a type mismatch so you do actually need the cast (int) there. Although going from int to double (the other way) you wouldn't.
The full textbook (704 pages) should be arriving in a few days, yay! So far I haven't had trouble with using the draft, though. I get the logic behind them, but writing complicated Boolean expressions can get somewhat challenging, last night I had to break a few of them down on paper to be clear about what happens, but it's fun.
@michaeldcurry1 I guess they did the double y = (double)x/2; formula and the answer is wrong :/... All they had to do was add parenthesis around the x/2.
+Laxman Bista you need to go to the start of these videos. There is a playlist.

I'm learning java on my own. These lectures and assignments have helped me learn a lot already. I just finished Assignment 2, problem 5. Would I be able to get feedback on my solutions to the problems even though I'm not enrolled in Stanford?
I mailed Mehran a question. He mailed me candy. True story.
its like a mixture of learning maths and a language at the same time! ... I NEVER thought id be doing that on my Christmas holidays!
You couldn't wish for a better teacher. Genuine, passionate, comprehensive, clear & actually quite funny. Sahami is my hero.
Mehran is the goat. Havent seen a professor as enthusiastic and involved as him yet.
Awesome work stanford, making this free is just fantastic.
"anyone know how george bool die?"
"he got set to false"
had to comment it ...
Simply outstanding. Professor Sahami is a gifted lecturer whose genuine interest in the subject and students comes through loudly and clearly.
Professor Mehran is a very dedicated and great teacher I wished I had him as a teacher.Some teacher may be knows the material but do not have the way to presented in a simple way................................Thanks for Stanford and Prof. Mehran

"We do it again, we get 1."
"We do 1 divide equal 2 we get...... 0 which is not greater than 1, so we're done."

The quotations are directly from the lecture.
