split a string using delimiter..truncate each segment and append

Hello.. this is my first post here ..I'll explain what I want to accomplish using an example

Suppose I have a string C:\check out\checking out\BACKUPER

Now I'll split it using delimiter as \ .
So it will become

C:

check out

checking out

BACKUPER

"check out" and "checking out" contain space.The code will remove the space and convert
them into "checkout" and "checkingout".

Then truncate them into strings of 6 characters and append ~1.

Finally they will be become checko~1 and checki~1.

BACKUPER doesn't contain space.So, it will remain as it is.

Finally all will be appended and result will be C:\checko~1\checki~1\BACKUPER

Can any one suggest me an approach or any function that will make this adventure like a cake walk ??

Thanks in advance ..

Welcome to the ranch !
If you look at the java.lang.String API, you'll have most (all?) of the tools you need.

Seems like you have all the steps--what, specifically, are you having a problem with?

Be careful with this algorithm, though--what would happen if you had these two directories?

c:\check out\foo
c:\check out this\foo

c:\check out this\foo

For the directories given by you ... according my algorithm it will be
c:\checko~1\foo
c:\checko~1\foo

As foo is devoid of space.

I was just looking for some tip or approach that will be quite easy.

Right, what I'm saying is that the two different directories would map to the same shortened string, which is a Bad Thing.

Ok.. In my case this kind of scenario won't arise.

hi ,

I hope this could help.
I tried to get the desired output.

@Raza: Please don't provide complete solutions. Our goal on JavaRanch is to help people learn how to learn, figure out problems, and so on--rather than just do somebody's work for them, encourage them to spend some quality time on it themselves, try various solutions, etc. Thanks.

okay Newton,

i will not do it again,
it was my mistake.

thanks

c:\checko~1\foo
c:\checko~1\foo

No, This must be like

c:\checko~1\foo
c:\checko~2\foo

java.lang.String API having this solution. Algo should be look like this

loop1 while mainStr not null
resArr[count++] = mainStr.slice(indexof("\\"))
end Loop2

loop2 while resArr

1. you can use selection/binary sorting here
2. truncate tailing chars with ~1
3. do compare array element for 8 char similar string.
4. if similar truncate tailing chars with ~2,3,4... so on

Apology accepted, on behalf of JavaRanch

You are not getting me .In my case there will be only one string and only ~1 has to be appended.
No question of ~2,~3,...

Thanks for your suggestion.
