With proper indenting it looks a lot better and doesn't need "end foreach"-like comments (if you ever feel you need comments that say what you're ending, fix your style instead!!).

Rule of thumb: always let the thing that causes the indentation be the last on a line. Another rule of thumb: align closing parens/brackets with the indentation of the line that caused indentation.
So don't use:

somefunction( foo(bar, "Hello World", ) // end of foo ); // end of somefunction
But instead use:
somefunction( foo( bar, "Hello World", ) );
You may or may not like it, but I find it much better readable.

import java.util.ArrayList; import java.util.Comparator; import java.util.List; import perlforjava.control.Looper; import perlforjava.functions.Arrays; import perlforjava.functions.Mapper; import perlforjava.lang.Block; public class TheSchwartz { public static void main(String[] args) { // Create a new List of values to sort ArrayList in = new ArrayList(); in.add("foobarbazquux"); in.add("foo"); in.add("foobarbaz"); in.add("foobar"); /* Sort based upon length of string by mapping each string to a List where the first element is the string and the second + is its length. Sort on the latter and return a new List of str +ings. */ List out = new Block() { // pull the first element from each List and return it protected Object process(Object elem) { return ((List)elem).get(0); } }, Arrays.sort( // run the comparison of Integer values to determine o +rder new Comparator() { public int compare(Object a, Object b) { return ((Integer)((List)a).get(1)). compareTo(((Integer)((List)b).get(1))); } }, // map each string into an ArrayList of string => leng +th new Block() { protected Object process(Object elem) { ArrayList temp = new ArrayList(); temp.add(elem); temp.add(new Integer(((String)elem).length +())); return temp; } }, in ) ) ); // Loop over the results to view them Looper.foreach( out, new Block() { protected Object process(Object elem) { System.out.println("ELEM " + elem.toString()); return null; } } ); } }

But indeed, Perl is much nicer towards programmers anyway.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
