Java? That's an awk script.

Could could put it on one line and use no comments and shorter variable names if you wish, e.g.

Code:
ls | awk 'BEGIN{if(!(w>0))w=80}length>m{m=length}{a[NR]=$0}END{c=int(w/++m);for(i=1;i<=NR;i++){printf("%-"m"s",a[i]);if(!(i%c))print""}if(--i%c)print""}'

You could implement the same algorithm easily enough in pure shell code or perl if you preferred.

You may be thinking of something like ls | paste - - - - (to format ls output into four columns, but that won't adjust the column widths to make them line up.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
