Chapter 9.1, Problem 1STQ
Explanation of Solution
Given code:
The given code is highlighted below.
//Main Class
class Main
{
//Main method
public static void main(String[] args)
{
//A variable is declared and a value is assigned
int waitTime = 46;
//Try block
try
{
//Print the message
System.out.println("Try block entered");
//Check if value is greater than 30
if(waitTime > 30)
//Throw an exception
throw new Exception("Time Limit Exceeded.");
//Print the message
System.out.println("Leaving try block.");
}
//Catch block
catch (Exception e)
{
//Print the exception

Write down the output of the program and justify why it is the output. Instead of the “replacement” semantics of exception handling used in modern languages, a very early design of exception handling introduced in the PL/I language uses a “binding” semantics. In particular, the design dynamically tracks a
sequence of “catch” blocks that are currently active; a catch block is active whenever the corresponding try block is active. What will be the output of the following program if the language uses the “binding” semantics? Give the reasoning for your answer.
Time Converter
1. Write a program that converts dates from a numerical month-day format to alphabetic month-day format. IE 1/31 or 01/31 would have an output of January 31.
1. User enters the month and day as a single string. It is then converted. (10%)
2. Create 2 exception classes (20%)
1. MonthException thrown for invalid months
2. DayException-thrown for invalid days for the given month
3. You can assume Feb is always 28 days
2. This should run in a for loop and end when a user is done entering dates (70%)
A throw statement - throw new Exception() - is used to throw an exception.
True
False
