You need to understand difference between Comparable and Comparator.

Comparable implementations provide a natural ordering for a class, which allows objects of that class to be sorted automatically.

Comparator is an object that encapsulates an ordering. You will use Comparator when you want to sort some objects in an order other than their natural ordering or when you want to sort some objects that don't implement Comparable.

Refer to http://download.oracle.com/javase/tutorial/collections/interfaces/order.html where this stuff is explained nicely.

In your case, Fruit is not required to implement Comparable. This should solve the problem

The class is right there in the same file (AbstractList.java), just search for "class SubList"
In my jdk1.6.0_16 it is at line 592

Oops , yes I interpreted the problem incorrectly, my apologies
Here is the sample program that will work. I hope I am correct this time.
I am running it in eclipse and "bin" is where my .class files are.

package test; public class Test { public static void main(String[] args) { System.out.println("Started"); for(String s : args) { System.out.println(s); } } } package test; import java.io.BufferedReader; import java.io.File; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; public class Test2 { public static void main(String[] args) throws IOException { String classesDir = new File(".").getCanonicalPath() + "\\bin"; Process p = Runtime.getRuntime().exec("java test.Test Foo Bar", new String[0], new File(classesDir)); InputStream in = p.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); String line = null; while ((line = reader.readLine()) != null) { System.out.println(line); } } }

Thanks Campbell Ritchie for the welcome

Hi Rajshkhr Pandey,
Do you mean in following example, when you run Test2.main() it is not printing anything?

------------------------------ public class Test { public static void main(String[] args) { for(String s : args) { System.out.println(s); } } } ------------------------------ public class Test2 { public static void main(String[] args) { String[] arr = { "foo", "bar" }; Test.main(arr); } } ------------------------------
It works for me
