Lecture 20 | Programming Methodology (Stanford)

[chattychar]

this is a special acm library and not the regular acm. proceed with caution. i learned this the hard way. this is a classroom novice version of java, specially formatted thanks to the help of their 'special' acm library. e.g he says the components will show up in the order in which they are added. this is not true in all layouts. this is only true in layouts like Boxlayout. in flowlayout you could end up putting all your components on top of eachother which is not good.

Hard to understand because of the poor sound quality.

this is not working for me. all i get is the applet window with the button and the console window in the center like it is supposed to ...but when i press the button nothing happens. i imported all the packages including the acm.program jar file and I am using the 1.7 JDK. it is typed out exactly like his. I am using the stanford eclipse version helios.

@chattychar

same problem here with eclipse in both windows/linux

[meesternadim]

i geet these 2 errors:

The method add(Component, int) in the type Container is not applicable for the arguments (GObject, int, int)

and:

The method add(Component, int) in the type Container is not applicable for the arguments (GObject, int, int)

How do i solve it?

[MechanismsMinecraft]

@meesternadim You just want to have add(GObject) :P Hopefully that helped your 2 month old project..

[meesternadim]

When i run the program, the appearing window is very small, when i enlarge it, the buttons disapear, how can i solve it and is there a way to start the application in the center of the screen and bigger?

for those who have difficulties in adding acm libraries should do:

-Right click on your project folder in the package explorer

-Choose "properties" at the bottom

-Choose "Java Build Path" and the "Libraries" tab there

-Click "Add External JARs..."

-Find where you saved the jar file and choose it

lol this is programming methodology, why the hell does he uses spaces to seperate controlls? yea its not wrong but especially in a class that teaches METHODOLOGY you shouldnt be doing things like that.

hmmm

It is a proprietary package for learning java and I don't think it is freely available. Also, Stanford foilks have edited the programming environment and made it optimal for learning methodoloy of programming and not necessarily the grammer of the language. That's the reason why they don't start stand-alone programs with 'public static void main()'. It is always a run() method, i.e. they are using threads under the hood... pretty neat i say!

can someone tell me where can i find this version of eclipse ? ... i tried all kinds of eclipse and all kinds of jdk ... even thoese from CS106A software .... but i still couldn.t import acm.graphics.*; or acm.program.*;

[TCPQD]

Hi aafsd1423,

Did you try to import the Karel assignment stuff and give it another go? It contains the acm libraries.

Other than that I love these classes.

[jgromero79]

If still needed,

acm package doesn't belong to eclipse neither to jdk. try to search acm.jar or copy that file as TCPQD says.

And yes great classes!
