Question

For this assignment, you will apply what you learned in analyzing a simple Java™ program by writing your own Java™ program. The Java™ program you write should do the following:

• Organize the code capable of throwing an exception of type ParseException as a tryblock.
• Include a catch block to handle a ParseException error thown by the try block.
• Include a hard-coded error that results in a ParseException to prove that the code can catch and handle this type of exception.

Complete this assignment by doing the following:

1. Download and unzip the linked Week 5 Coding Assignment Zip File.
2. Add comments to the code by typing your name and the date in the multi-line comment header.
3. Replace the following lines with Java™ code as directed in the file:

• LINE 1
• LINE 2

1. Replace the value assigned with one of the variables so that the program throws an exception.
2. Comment each line of code you add to explain what you intend the code to do. Be sure to include a comment for the replacement value you added in Step 4 that causes the program to throw an exception.
3. Test and modify your Java™ program until it runs without errors and produces the results described above.

public class PRG420Week5_CodingAssignment {

public static void main(String[] args){

// The getInstance() method returns a Calendar object whose calendar fields have been initialized with the current date and time.
Calendar calendar = Calendar.getInstance(); {

LINE 1. BEGIN THE TRY BLOCK.
  
String str_date="01-Nov-17"; // Declare a string that we will use later to format a date like this: ##-XXX-##
DateFormat formatter; // Declare an object of type DateFormat so that we can call its parse() method later
Date myFormattedDate; // Declare a variable of type Date to hold the formatted date
  
formatter = new SimpleDateFormat("dd-MMM-yy"); // Assign a specific date format to the formatter variable

// The given date is taken as a string that is converted into a date type by using
// the parse() method

myFormattedDate = (Date)formatter.parse(str_date);     // setting up the format
  
System.out.println("The formatted date is " + myFormattedDate);
System.out.println("Today is " +calendar.getTime() );
  

LINE 2. WRITE THE CATCH BLOCK TO CATCH EXCEPTIONS OF TYPE ParseException (TO HANDLE EXCEPTION, SIMPLY PRINT THE EXCEPTION)

  
}
}
}

Answer 1

I am giving date in wrong format to show the exception in console output.

Please give date in right format to print the date and time .

import java.text.*;
import java.util.*;

public class PRG420Week5_CodingAssignment {
  
   public static void main(String[] args){
       Calendar calender=Calendar.getInstance();
      
       try{
           String str_date="2019-3-Nov"; // date is in wrong format
          
           DateFormat formatter; //Declaring Dateformatter
           Date MyFormattedDate;
           formatter=new SimpleDateFormat("dd-MMM-yy"); //Declaring Dateformat
           MyFormattedDate=(Date)formatter.parse(str_date); //formatting wrong date. this line will throw ParseException
           System.out.println("The formatted Date is "+MyFormattedDate); //printing Date
           System.out.println("Today is "+calender.getTime()); // printing Time
          
       }catch(ParseException e) {
e.printStackTrace();
           }
       }

}
