Program Plan Intro

Shipping cost

Program plan:

Filename: “InsuredPackage.java”

Define of “InsuredPackage” class

Define constructor

Call the “super” method

Declare the constant variables with the values.

Check “getCost ()” is less than “LOWCOST”

Set “i” is “LOWINS”

Check “getCost ()” is less than “MEDCOST”

Set “i” is “MEDINS”

Otherwise, set “i” is “HIGHINS”

Call the “increaseCost()” method.

Filename: “Package.java”

Define the “Package” class

Declare the required private variables

Define the parameterized constructor

Set the values

Call the method

Define the “calculateCost” method

Declare the variable

Check “w” is less than “LOWWT”

Check “m” is equal to “AIR”

Set “c” is “LOWAIR”

Otherwise, check “m” is equal to “TRUCK”

Set “c” is “LOWTRUCK”

Otherwise, set “c” is “LOWMAIL”

Check “w” is less than “MEDWT”

Check “m” is equal to “AIR”

Set “c” is “MEDAIR”

Otherwise, check “m” is equal to “TRUCK”

Set “c” is “MEDTRUCK”

Otherwise, set “c” is “MEDMAIL”

Check “w” is less than “HIGHWT”

Check “m” is equal to “AIR”

Set “c” is “HIGHAIR”

Otherwise, check “m” is equal to “TRUCK”

Set “c” is “HIGHTRUCK”

Otherwise, set “c” is “HIGHMAIL”

Return the value

Define the “display” method

Display the result

Define the “getCost” method

Return the cost

Define the “increaseCost” method

Calculate the cost value

Filename: “UsePackage.java”

Define the “UsePackage” class

Define the main method

Create three objects for “Package” class with different values

Create three objects for “InsuredPackage” class with different values

Call the “display” method with different objects of “Package” and “InsuredPackage” classes.

Question 2 (10 Points): String vs. StringBuilder Create a Question2.java file and finish the following tasks: Task 1. a) Create a 1D array of integers to store 50 integers. b) Store values from 0 to 49 in the array you just created. c) Create a new String Object using no-arg constructor. d) Using for loop to add the array elements one by one to the String (one per loop iteration) Hint: to append an element to a String, use the + operator. e) Output the String on the console. Record and display a run-time it took to append all integers to the String (record run-time of 1.d.)). Please submit a screenshot. The screenshot should match the following example: 012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849 it took 196708 nanoseconds to append 50 integers to the String.| Hint: You can use the following statements to record run-time. long begin, end, time; // we will measure time it took begin = System.nanoTime(); //we measure in nanoseconds. // put…
