NoSuchMethod error ?

[Dean Bright]

Im a little confused as to why I am getting the following error at runtime :

Exception in thread "main" java.lang.NoSuchMethodError: Dog.<init>(Ljava/lang/String;)V
at IteratorTest.main(IteratorTest.java:10)

Here is the source code, saved as IteratorTest.java, it is an example from K&B pg580, I've just decided to play around with it a bit however even copying the code exactly it doesnt seem to work.

import java.util.*;
class Dog {
	public String name;
	Dog(String n) { name=n; }
}

class IteratorTest {
	public static void main(String[] args) {
		List<Dog> d=new ArrayList<Dog>();
		Dog dog=new Dog("Aiko");
		d.add(dog);
		d.add(new Dog("clover"));
		d.add(new Dog("magnolia"));
		Iterator<Dog> i3=d.iterator(); // make an iterator
		while(i3.hasNext()) {
			Dog d2=i3.next(); 	//Because we used the generics syntax to create
							// the Iterator(of type Dog) no cast is required
			System.out.println(d2.name);
		}
		System.out.println("size "+d.size());
		System.out.println("get1 "+d.get(1).name);
		System.out.println("aiko "+d.indexOf(dog));
		d.remove(2);
		Object[] oa=d.toArray();
		for (Object o : oa) {
			Dog d2=(Dog)o;
			System.out.println("oa "+d2.name); 
		}
	}	
}

Please => UseCodeTags <=, Use the EDIT button to edit it and put the code tags! It'll be more readable!

There are no problems, works fine!

Thanks, just tried it again myself from the command line and it works 100% .... the problem occurred whenever running it directly from my IDE, JEdit which is how I have been doing things for every other bit of code I have wrote. Thanks for the quick responses.

May be that IDE have its own compiler!
