    {
        try /* Line 5 */
        {
            throw new Exception(); /* Line 7 */
        } 
        finally /* Line 9 */
        {
            System.out.print("finally "); /* Line 11 */
        } 
    } 
    public static void main(String args[]) 
    {
        try 
        {

        } 
        catch (Exception e) /* Line 20 */
        {

What will be the output of the program?

public class MyProgram 
{
    public static void main(String args[])
    {
        try 
        {
            System.out.print("Hello world ");
        }
        finally 
        {
            System.out.println("Finally executing ");
        }
    }
}
