4. The Big One

by CodeChum Admin

Remember that time when we've tried identifying the largest digit among the given integer? Well, let's take it to the next level, and figure out the same thing on arrays/lists!

Let's do this one more time!

Instructions:

1. Create a variable that accepts a positive integer.
2. Create an empty list. Then, using loops, add random integer values into the list one by one. The number of values to be stored is dependent on the inputted positive integer given in the first instruction.
3. Print out the largest integer among all the elements on the list, by any means necessary.

Input

The first line contains the size of the array/list.

The next lines contains an integer on each.

5
34
3
23
10

Output

A line containing an integer.

A company dealing with marketing wants to manage the data of its employees. Each employee has a full name, unique employee number (2019000 to 2019999) and the number of hours he worked and her hourly wage (price).

(Using Encapsulation)

Create a class named 'Student' with 2 instance variables (both set as private)

 The 2 variables are: String variable 'name' and integer variable 'roll_no'.

 Create a get and set Method for each variable.

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

 Create an object of the class Student

 Allow the user to enter a value for the name and roll_no and accept the values by using

the set Method of each variable

 Display the content of the object by using the get Method of each variable

(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.

Modify the given codes to remove the compilation errors. (2 items x 5 points)

1.

public interface Carnivore {

int pieces = 10;

public static void eatGrass();

public int chew() {

return 13;

}

}

2.

interface Haswings {

public int getNumberOfWings();

}

abstract class Insect implements HasWings {

abstract int getNumberOfLegs();

}

public class Dragonfly extends Insect {

int getNumberOfLegs() {

return 6;

}

}

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.
