Get and swap commands

[CooLiBoP]

I was just wondering how my program will know the user typed a command swap or get because on the same like they are supposed to type numbers along with it...

i.e. if(x.equals("get")){
...
}

but how do I include the numbers after they type like "get 2"?

look for a space in "x" , use substring???., i can't really remember,,., anyways.,
once u find a space in String "x" ,  your index would be wherever the space is,,., then u take the values after that space to the length of the String x, ?? and turn it into an int?

for swap, same deal , but instead of going to the length of the string X for the first value, u goto the next space..,

is this a valid way of doing it?.., i don't like to do it this way but i can only think of this.,..,,. any other suggestions? , an easier way?

for the swap command,.
when it swaps indices i and j,
do they mean that if i have a vector of URLs followed by its title on the next index,
that i can swap the location of the url and its title with another url and its title so kinda like this:
where the numbers depict the indices

if i do swap 2 3 wouldn't i have:
1 www.utoronto.ca/
2 mat137.proboards.com/
3 U of T Website
4 MAT137 Help Forum

or do the indices only apply to the url + title so that when swapping i acutally add 1 to index to get both the url line and its corresponding title line??

am i making this harder than it really is???,

ur probably supposed to do it the way that makes sense, i.e., always keep the url and its corresponding title together.

check the String class in the api.. there's a method that might make things a bit easier..

On the hints page (the link above the handout on the CSC148 page) it says that there will be URL and title at each index in the question about swapping. WTF? I have my URLs as one element followed by the title in the next, I hope they don't mean what they've written.

[Brutal_Chicken]

Hmm, well I suppose creating two vectors instead of one might be what they wanted but I just put it all in one vector.

There will indeed be a url and title at both indices.

I'm changing my code so that I'd have to deal with two vectors in the appropriate indices rather than have some confounded way to get both URL and List.

[Observer]

Indeed that is what I am doing, this is a real pain.

[Brutal_Chicken]

URLList should have as an instance variable a reference to a List object from package java.util, such as ArrayList or Vector. (Which one you use is up to you.)

Note the singular referrence to a Vector or ArrayList. I think they do want it all in list.

Which brings me to my question; How to convert Integer to an int? Or more precisely, string to an int.

I've substring'd the part of the string where the numbers are supposed to be but I can't convert them to ints for the life of me. I've tried Integer.parseInt(substring) and several other weird conversions in between.

[1.8T]

are we suppose to save url in one index and title on the next??

but wouldn't it be easier if we store both on one line as one  element of a vector.,
and when we need to output., we split it up?.,
cuz the swap and get commands will be hard to make., since u hafta make the indices of the title correspond to the url,
and when outputting to a html file., the url and title are on the same line anyways.,
anyone did it this way?

[Sylph]

i did it 1.8T's way. ;D everything works now.. except i have to start URLListTester.

it should be Integer.parseint <--- Notice NO CAPITAL I
Its not Integer.parseInt ... its Integer.parseint!

[Observer]

That certainly makes it easier.

why doesn't Integer.parseInt work? it works for me..

[Brutal_Chicken]

Well I tried parseint but the parseint method isn't in Integer, but parseInt works fine (not counting this case). Besides, why would parseint be a legal method that defies the syntax convention of java?
