Assume that I
have a class Base whose constructor looks like this:
public Base()
{
foo();
}
where
foo is a method that may be overridden by a derived class if desired. The
body of the foo method contains no code (empty). Also,
I
have a class named Derived which inherits from the above mentioned
class.
It has one field
private SomeClass obj = new
SomeClass();
where
SomeClass is a class with a method named “method.”
Derived
overrides the base class method foo with the following
implementation:
obj.method();
Now,
what is the effect of creating an object of Derived using
new Derived();

Quiz from the past issue
This one should be easy. Given the following Java code
exerpt:
{ foo(); // foo may throw an Exception doSomeThing(); doSomeThingElse(); //... rest of the code }
I want doSomeThing() to be executed irrespective of whether foo throws an
exception or not. What is the minimal code I should write to achieve this?
Answer!
Thanks to those who wrote to us with a response to this quiz. Your names
have been entered for the year end drawing! Surprisingly none of the responses
received initially were correct! Almost every one consistently said write a catch
and finally. While the hope was sliming down, Craig, one of our new subscribers,
finally came with the correct answer!
The answer is:
{ try { foo(); // foo may throw an Exception } finally { doSomeThing(); } doSomeThingElse(); //... rest of the code }
