Did anyone come accross this problem:

You have an interface defining a method (e.g. getInt())

You have an abstract class implementing this interface

but not the method.

You have an object implement this abstract class.



When using the method defined in the interface through

the abstract class you get an annoying:

java.lang.AbstractMethodError



like this:

			ITest.java:
			

			public interface ITest {
			

			int getInt();
			

			}
			

			

			AbstractTest.java:
			

			public abstract class AbstractTest implements ITest{}
			

			

			SimpleTest.java:
			

			public class SimpleTest extends AbstractTest {
			

			public int getInt() {return 1;}}
			

			

			Test.java:
			

			public class Test
			

			{
			

			public static void main(String[] args)
			

			{
			

			use(new SimpleTest());
			

			}
			

			static void use(AbstractTest test)
			

			{
			

			test.getInt();
			

			}
			

			}
