I'm not seeing the output from my class now (I know this is a
simple/stupid thing on my part), what am I doing wrong:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.util.ArrayList;

import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.Task;

public class LineCounter extends Task
{
	public String filename;
	public void Execute() throws BuildException
	{
		LineCounter lc =3D new LineCounter();
		log("about to call countlines");
		log(filename+ " contains " +
lc.countLines(this.filename) +" lines.");
	}
	public void setFilename(String filename)
	{
		System.out.println("we are about to parse ->"+filename);
		this.filename=3D filename;
	}
	public int countLines(String file)
	{
		ArrayList integlist =3D new ArrayList();
		try=20
		{
			BufferedReader br =3D new BufferedReader(new
FileReader(new File(file)));
			String line;
			while((line =3D br.readLine())!=3Dnull)
			{
				integlist.add(line);
			}
			System.out.println(integlist.size());
			br.close();
		}
		catch (Exception e)=20
		{
			e.printStackTrace();
			System.exit(-1);
		}
		return integlist.size();
	}

}

> Is there any good way to count how many lines in a file there is?

You could also write a simple, custom Task to do this; see the online=20
Ant manual for guidance...
