Hi I am struggling learning perl and everytime I try to enter stuff in at runtime I keep getting a 1 returned. I dont get it. please can you explain to me what I am doing wrong.


...

got it. You cant put calls to subroutines in print statements because it already executes them anyway.

I am trying to teach myself perl and I cannot understand why when I print arrays from these subroutines that it prints an extra one that isnt there.

@name=fname(@name)."\n".lname(@name);

thnx m8. I have solved it. Your spot on. I wasnt using my methods properly. once I have handed the homework in I will post my solution if ur interested. Until then this is a solved thread and I think...

I changed it in my rectangle class but I am still getting 0.0 when I run my driver class.

Hi guys I am now onto my driver class and it is causing me issues. I need it to show that it can print out the correct area and for the style for the triangle. for the rectangle I just need to print...

hmm good idea. Then see if you get head hunted by a rival company. Then you will be taken much more seriously. Yeah start putting some neat programmes on the web. Make all sorts of stuff either games...

I have to create the rectangle class. I can't inherit it from triangle.

That TwoDShape class I can't change. That was given to me by my lecturer to do this work. the only other things If I have questions they will be on 3 things

Thnx. I am not marking this thread as solved yet because I may have other questions but that means I can now do a big chunk of my coding :-) thnx

don't use stringTokenizer cus that is being wiped out. Use Split. Go to the java API and it will tell you how to use it.

I am currently working on something where I have to make two shapes which extend to a class called 2d shape. I am currently working on my Triangle class which is this:

Something I have noticed with my uni course is that there are so few women on it. Is there some reason why women stay away from the best part of using a computer IE programming in java?

to convert a string to an real number which you will need with your conversions use double num = Double.parseDouble(enteredString);

well for starters your emp_pos is null also you a_pos isnt defined as anything so try

a_pos = "lol";

emp_pos = a_pos;

then see if that works.

To print in something like a table format on the command line use "/t" and "/n" in System.out.print();

If you want a table format using a gui then look at the libraries on the JAVA API website.

sounds to me like a system like that needs to be made using cobol.

object orientated programming is using objects to code so as to remove the need for global variables, create better securer code and programming at a higher level than that of machine code.

int num = Integer.parseInt(parseString)

thnx guys for your help my work is solved.

Thanks a million guys. I am almost there. I have an out of bounds exception -1 though which I dont understand. this is my code and I have included both my classes.

For the guys who helped on the card.java file I did thnaks a lot I got that done. I have now moved onto the next part of that and have to complete this skeleton file.
this is the spec for this file....

thanks both of you. Ezzaral you said I couldn't call the getter methods in the Card class. Is that because getter methods can only be called in a main method?

right I am trying to practice with my programming taking my lectures advice and breaking the problem down into steps, then when I code, code a small amount, compile it check it works and then code...

okay I didnt think of that. thnx. I will bare that in mind.

so stupid. I know what help I can get for my homeworks. I dont know who that was who sent that. I always state if its a homework. There is a level of help you can get. So long as I am not plagerising...

I decided to take the other approach with this cus I cant use the scanner class to save my life. So instead I have decided to use substring. My thought it if I separate a string in two then I can...

okay I have made a revision of my code. I know nothing is being outputted in my main class but have I created the new sentence? this one is a real head scratcher for me.

I have been given a homework this is it:



I have chosen to attack this problem using the scanner class. The problem I have is at runtime just the word "word" is printed loads and loads of times...

I finally got it :-D Thanks a lot you really helped.
