Question

1. What is the minimum modification needed to make the code that follows compile?

public void readData() {
    boolean dataNotFound = true;
    if (dataNotFound) {
        throw new IOException();
    }
    catch(IOException e) {
        System.out.println("data file can't be found");
    }
}

a.	Place the if statement within a try block.
b.	Add a throws clause to the method declaration.
c.	Set dataNotFound to false.
d.	No modification is needed.

Answer 1

a)
Place the if statement within a try block.

Explanation:
-------------
this method has a catch block. so, there must be a try block preceding it.
so, we need to put entire if block inside a try block

Fixed code:
------------
public void readData() {
    boolean dataNotFound = true;
    try {
        if (dataNotFound) {
            throw new IOException();
        }
    } catch (IOException e) {
        System.out.println("data file can't be found");
    }
}
