Exceptions - Pointing out the correct statements 

  1. public class MyProgram 
{
    public static void throwit() 
    {
        throw new RuntimeException();
    }
    public static void main(String args[])
    {
        try 
        {
            System.out.println("Hello world ");
            throwit();
            System.out.println("Done with try block ");
        }
        finally 
        {
            System.out.println("Finally executing ");
        }
    }
}
    which answer most closely indicates the behavior of the program?
    2. A.

    The program will not compile.
    B.

    The program will print Hello world, then will print that a RuntimeException has occurred, then will print Done with try block, and then will print Finally executing.
    C.

    The program will print Hello world, then will print that a RuntimeException has occurred, and then will print Finally executing.
    D.

    } 
}
    At Point X on line 5, which code is necessary to make the code compile?

  3. System.out.print("Start ");
try 
{
    System.out.print("Hello world");
    throw new FileNotFoundException();
}
System.out.print(" Catch Here "); /* Line 7 */
catch(EOFException e) 
{
    System.out.print("End of file exception");
}
catch(FileNotFoundException e) 
{
    System.out.print("File not found");
}
    and given that EOFException and FileNotFoundException are both subclasses of IOException, and further assuming this block of code is placed into a class, which statement is most true concerning this code?
    4. A.

    The code will not compile.
    B.

    Code output: Start Hello world File Not Found.
    C.

    Code output: Start Hello world End of file exception.
    D.
