Question 72.
Read the following piece of code carefully.
import java.io.IOException;
public class Question72
{
public Question72() throws IOException
{
throw new IOException();
}
}
Assume that the defination of Question72E begins with the line
public class Question72E extends Question72
It is required that none of the constructors of Question72E should throw any checked exception.
1. It can be achieved by placing the call to the superclass with a super keyword , which is placed in a try block with a catch block to handle the IOException thrown by the super class.
2. It can be achived by avoiding explicit calls to the base class constructor.
3. It cannot be done in the
Java Laungage with the above definition of the base class.
