Created attachment 161530 [details] Error Product Version: NetBeans IDE Dev (Build 201606280002) Java: 1.8.0_60; Java HotSpot(TM) 64-Bit Server VM 25.60-b23 Runtime: Java(TM) SE Runtime Environment 1.8.0_60-b27 System: Windows 10 version 10.0 running on amd64; Cp1250; pl_PL (nb) 1. Create a class which extends java.util.Date: public class NewClass1 extends Date { private static final long serialVersionUID = 1L; } 2. On the class name you will have a hint to implement clone() - do it: public class NewClass1 extends Date { private static final long serialVersionUID = 1L; @Override public Object clone() { return super.clone(); } } 3. On the clone() method you will see a hint to declare CloneNotSupportedException - do it: public class NewClass1 extends Date { private static final long serialVersionUID = 1L; @Override public Object clone() throws CloneNotSupportedException { return super.clone(); } } 4. You end up with an error, because the overridden method does not throw CloneNotSupportedException.
