Sounds like you could be doing Java. There are loads of sites out there that help you and loads of helpful books as well. But I'm not gonna link to those or give you the names of books because everyone can use a search engine. The easiest way you could possibly learn is by paying attention and actually doing some programming. It's no good trying to justr read how to program you have to do it again and again and again untill the penny drops. Put the work in and you'll be fine.
Oh ok so here's a link that I use a lot:
http://www.boards.ie
and another:
http://p2p.wrox.com
and:
http://www.ijug.org
and of course:
http://java.sun.com0 -

Probably worth your while getting to know JSP too, even if it's not covered in the course. It's what used in the industry when it comes to Java and webdesign. Applets aren't so popular.
Check out Tomcat (http://jakarta.apache.org/tomcat) and the JSP forum on http://developer.java.sun.com
Other good places to look are:
http://www.jspin.com
http://www.onjava.com
http://www.serverpages.com
http://www.jspinsider.com
http://www.javaworld.com

My god! Zippy! That thing used to freak me out so much!

Ah it's just me really I'm always slow to post to boards. It took me ages to get started here. Didn't mean there was anything wrong or particularly intimidating about IJUG and personally I think it's the best thing since somebody decided to toast sliced bread! I tried starting up a JUG of my own ages ago (before IJUG was up I think) for students learning Java so we could all help each other out.
Anyway thanks for the advice. I'll probably post there soon enough.
Ah here it is! --> http://servlet.java.sun.com/jugs/europe/irl/clonmel,_co._tipperary0 -
I have a christmas test next monday (17-12-2001)on java. We are allowed to bring in a 2 sided a4 sheet with ANYTHING we want on it, the test is a written one, I'm trying to find out what is best to put on it!!! e.g. theory/programs???
The questions are on...
Q1 ifs and switchs
Q2 objects and methods
Q3or4 if statements
Q5 arrays
parts a+c = theory part b = programming(every question!
I'm doing 1st year software development so I wouldent say that the questions will be tricky, any help welcome!!!
Thanks, Willie0 -
You jammy.......... Well this should be a doddle. The amount of info you can fit on an A4 page!
Basically I'd put on anything that helps you understand the things. Plus if you have to write sample programs in your test, I'd include an example of the syntax you'd use, ie for if statements, for method implementations, for switch statements (especially) and for object declarations. Include some info on arrays as well, ie what the story with indexing is, and the different ways of declaring and initializing them. If you don't understand any of the jargon Ive used here then go and do some study!!!! 0 -
I nearly **** myself while reading this thread, I didn't recognise your initial startup post, so I was in for quite a shock when I noticed that I had posted (twice) myself. I thought I left my machine logged in, over in the college (Christ panic is over, TG :rolleyes: )
Anyway, having read this thread for a second time now, I feel that I jumped to the applet conclusion a little too fast. If your lecturer was talking about web applications, I am pretty sure he didn't mean applets. He was talking about Servlets or JSPs. In summary Servlets & JSPs (web applications), are the programs that sit on a web server, and process for input, e.g. "Enter your username/password and submit, on the hotmail login screen". HTML is what you use to create the form, and the web applicaton takes the forms contents and does something weird and wonderful with it.
Anyway, now for an up to date post.
Your exam shouldn't be that difficult if that is the exact topic layout of the paper. So let me elaborate...BTW I am going to keep this as easy as I can, coz you sould like you're struggling, and the last thing I want is for me to type a load of rubbish, when I could be doing something else.
Q1 (if/switches)
All an if/switch does is branch program flow
E.g.
IF yourAge isEqualTo 18
// Do this
ELSE
// Do that
Here is an example of some java code that demonstrates if/switchespublic class myExample{ int yourAge; public static void main(String[] args){ yourAge = 18; // Below is the IF/ELSE example if(yourAge == 18){ System.out.println("You are 18"); }else{ System.out.println("You are not 18"); } // Below is the SWITCH example switch(yourAge){ case 18:{ System.out.println("You are 18");break;} case 19:{ System.out.println("You are not 18");break;} } // That's it!, but just remember you can't use switch for comparing Strings, that's all. } }
Q2 (Objects/methods)
Quick theory and code
E.g.
Frame myFrame = new Frame();
myFrame.setSize(640, 480);
class: This is best known as a template for an object (In the above code, Frame is the class)
object: This is an instance of a class (In the above code, myFrame is the object)
method: This is best though of as the code within a class, that defines what it can do. (In the above code, setSize is the method or function, of the object myFrame, which is in turn an instance of the class Frame).
Getting the hang of it yet?
Q3 I would check that out again, coz I doubt they would give you two whole questions of program flow with if statements
Q4 (arrays]
Quick theory and code
array: This is a collection of variables or objects of similar data types or class, contained in a single entity. What the hell does that mean? (let us look at some code)
E.g.
int array[10];
The above line of code declared an array of integers with 10 elements. Remeber that array elements start at element zero, not one. But if it starts at element zero, isn't there going to be 11 elements in the above array. The answer is no, because the last element is a null pointer, that indicates the end of the array. The eleventh element would be
array[10]
You could initialise the elements using a loop
E.g.
int counter=0;
while(array[counter] != '\0'){
array[counter] = counter;
counter++
}
// it would be array[counter] != null if array was an array of objects as opposed to primitive data types such as int.
The end
Anyway dude I hope this was of some help to you, and good luch in the exam.

I hate to be a nit-picker, but he'll want everything right going into the exam.
In C++ that'd work, but Java would beint array[10];
The above line of code declared an array of integers with 10 elements.
int array[]=new int[10];
Kudos to phobos for giving the guy such a helping hand 0 -
