String[] to File[] 2

[aswolff]

Hi,

I have a property variable which contains a pipe seperated String of file names. I want to take that list of file names and create an array of File objects.

My code is

String xsls = properties.getProperty("xsls");
File [] xslfiles = xsls.split("\\|");
[code]

I get the following error:

WebApplicant.java:43: incompatible types
found   : java.lang.String[]
required: java.io.File[]
                File [] xslfiles = xsls.split("\\|");
                                             ^
I understand the error...split returns a string[] and I am trying to stuff it into a File[].  But how can I solve?

Thanks.

My solution was this..which is OK i guess...still curious if anybody has another way of accomplishing the same thing without a loop.

Thanks.

String [] xslArr = xsls.split("\\|");
File [] xslfiles = new File[xslArr.length];
for (int i = 0;i < xslArr.length; i++)
{
xslfiles[i] = new File(xslArr[i]);
System.out.println(xslArr[i] + "->" + xslfiles[i].getName());
}

You'll probably need to iterate through the String array. something like

String[] s = xsls.split("\\|");
for (int i = 0; i <  s.length; i++){
 xslfiles[i] = new File(s[i]);
}

Just a suggestion: maybe you don't need the File array, and you can use the String array deeper in the code and instantiate File objects just when you need to use it.

Cheers,

I agree with Dian. Although your code is 100% correct it could be a better idea to create the File objects when they are really needed.


Example:

String[] files = xsls.split("\\|");

for (String s : files){
doSomethingWithTheFile(new File(s));
}
