(Using Inheritance)

Create a parent class named “Parent”, with a method that displays “I am a Parent Class”.

Also create a subclass that named “Child” that has a method that prints “I am a Child Class”.

Now create a class with Main Method, where you will:

 Create an object for each class (1 for “Parent” and 1 for “Child”)

 Call the method of “Child” class by using the Child object

 Call the method of “Parent” class by object of the “Parent” class

1.Write a Java program that calculates and prints the monthly pay for an employee. The net pay is calculated after taking the following deductions:

Witholding 15%

SSS contribution 3.63%

Medicare 1.25%

Pag-IBIG PHP 100.00

2.Initialize two (2) variables to hold the employee name and the gross pay (amount before deductions). See sample output below:

Employee Name: Jess Diaz

Gross Pay: 25000.0

Deductions Amount

Witholding Tax 3750.0

SSS Contributions: 907.5

Medicare: 312.5

Pagibig Contribution: 100.0

Net Pay: 19930.0

Instructions:

Create a variable that accepts a positive integer.

Create an empty list. Then, using loops, add string values to your list using the input() function. The number of string values to be added are dependent on the inputted value on the first inputted integer.

Create another variable that accepts a non-negative integer. The number must only range from 0 until the value of the first inputted integer.

Using your understanding on accessing list elements, access and print out the list element having the index position of the second inputted integer.

Input

The first line contains an integer n which is the size of the array.

The next n lines contains a string on each.

The last line contains an integer which is the index to be accessed and printed.

Create a Hierarchy chart that will accurately represent the information in the scenario below: “A main programme calls three modules: getDetails(), calculateFees(), and register(). The calculateFees() module calls a module called courses() and a module called courseCost(). The register() module calls a module called printProof().”

By making use of pseudocode, show the programming statements that will

accept two values from a user. These two values should be added together, and

the result displayed on the screen

On the form, create two combo boxes, to allow a user to select between three

different printers and years. When a user has selected a printer and year and clicked

the submit button, display the amount of ink cartridges used for that year. Use the

following table for the printers and yearly cartridges used:

2018 2019 2020

HP Deskjesk 650 10 35 20

Epson K750 15 22 12

Canon Z100 30 31 33

Q.1.2 You are also required to create a menu system which will allow the user to exit the

application under the file menu. Under the tool’s menu, allow the form submission

and an option to display the yearly ink cartridges used for each printer. The layout

of the form is left to your discretion. Marks will be allocated to the presentation and

effectiveness of the layout, but the following layout is displayed for your

convenience.

Write a Java GUI application that will keep track of a company’s products. The application must

contain the product id, product name and the product price.

Q.3.1 On the form, create three text fields to capture the product details and a non‐

editable text area to display the product details. Create a submit button that

when clicked will save the product details to a Products.txt file. Also include a

search button that will allow a user to search for a product based on the product

id.

Q.3.2 Create a sequential file (products.txt) that contains data for the following fields:

 The product id

 The product name

 The product price
