Hi ,

I have tried to create java.lang.AbstractMethodError from table 9-4 as mentioned in the exercise.
Here's how i was able to create the error:


here's the code:
#1 created and compiled an interface
package com.rohtakdev.chapter9; public interface Glass{}
#2 Implemented that interface and compiled it.
package com.rohtakdev.chapter9; import com.rohtakdev.chapter9.Glass; public class GlassCup implements Glass{ }

#3 Then changed interface to have a new method and compiled; didn't compile inplementing class.
package com.rohtakdev.chapter9; public interface Glass{ public void something(); }

#4 created a class with main method, initialized class and called new interface method.

package com.rohtakdev.chapter9; import com.rohtakdev.chapter9.Glass; import com.rohtakdev.chapter9.GlassCup; public class MainGlass{ public static void main(String[] args){ try{ Glass glass = new GlassCup(); glass.something(); }catch(AbstractMethodError ame){ System.out.println("caught exception "+ ame); } } }

I was able to successfully catch the exception.

Thanks for a great book.
