Hello,

I'm reading a file that look like this:

drwxr-xr-x 8 user staff 512 Nov 28 16:17 build
drwxr-xr-x 2 user staff 512 Nov 28 16:17 build.xml

and I want to use permission, file size and file name.
ex.(drwxr-xr-x, 512, build)

Right now I'm using nextToken() to get the token I want.
Is there a simpler way to replace these code? such as make the line into array of tokens??

Thank you so much,

StringBuffer str = new StringBuffer();

System.out.println(st1.nextToken());
st1.nextToken();
st1.nextToken();
st1.nextToken();
System.out.println(st1.nextToken());
st1.nextToken();
st1.nextToken();
st1.nextToken();
System.out.println(st1.nextToken());

Why not simply split on the white space? The information you're interested in is in index 0, 4 and 8.

Thank you, this is exactly what I'm looking for.

However, using String[] tokens = "drwxr-xr-x 8 user staff 512 Dec 1 13:19 .".split("\\s"); I get token.length == 23.
I have also tried other split, but doesn't work.

any ideas?

drwxr-xr-x 8 user staff 512 Dec 1 13:19 .

Ah yes, the forum probably merged all multiple spaces to a single one.
I see you have found the right solution! Well done.
