need some help with this java program

By using Programming Assignment 2 solution which is below, where your program must have been written using methods, constructors and objects, you are to rewrite it to accomplish the following tasks for this assignment 3.

Part I

Text I/O [Additional input]: You should enter a shipping companys Name, Address, quantity of parcels shipped in each weight bracket. The output should be stored in a file (). Your output on the file should be descriptive.

The Output should contain the following:

Companys: Name and Address

Weight Bracket: Quantity Shipped

Cost of shipping to: Canada, USA, Europe or South America

Total Cost: For all Quantity of goods shipped

Part II

Exception handling:

Only accepted input should be entered, all other error and/or exceptions should be handle and the user allowed to re-enter the correct input only up to 3 times. If the user enters incorrect entry twice, the program warns him as

All output should be free of errors and well formatted.

If correct input is entered, the user could be asked to terminate the program or allowed to enter different input. All entries made by the user should be saved into the text file.

Part III

Comments: Provide comments to your code using Javadoc, class header comments, and section and method comments describing the task the section/method is performing.

Select a shipping location: 2

Enter the number of packages shipped or 0 if no packages.

Packages of weight range 0 < w <= 1: 4

Packages of weight range 1 < w <= 3: 7

Packages of weight range 3 < w <= 10: 2

Packages of weight range 10 < w <= 20: 4
