Exception and Inheritance in JAVA
- by user1759950
Suppose we have this problem
public class Father{
public void method1(){...}
}
public class Child1 extends Father{
public void method1() throws Exception{
super.method1();
...
}
}
Child1 extends Father and override method1 but given implementation Child1.method1 now throws a exception, this wont compile as override method can't throw new exceptions.
What is the best solution?
Propagate the required exception to the Father.. to me this is against encapsulation, inheritance and general OOP ( the father potentially throw and exception that will never happen )
Use a RuntimeException instead? This solution wont propagate the Exception to the father but I read In Oracle docs and others sources states class of exceptions should be used when "Client code cannot do anything" this is not that case, this exception will b useful to recover blablabla ( why is wrong to use RuntimeException instead? )
Other..
thanks,
