Build a simple “English Language” calculator that does the following:

●    Takes three inputs from the keyboard

●    Two of the inputs are single-digit numbers (0 to 9)

●    The third input is a char from the keyboard, representing one of the five operations from the keyboard:

○    + (addition)

○    - (subtraction)

○    * (multiplication)

○    / (division)

○    ^ (exponentiation)

●    Output the description of the operation in plain English, as well as the numeric result

Write a program that reads a web address (for instance, www.yahoo.com) from the keyboard and outputs whether this web address is for a government, a university, a business, a non-profit organization, or another entity.

●      If the web address ends with gov, it is a government web address.

●      If the web address ends with edu, it is a university web address.

●      If the web address ends with com, it is a business web address.

●      If the web address ends with org, it is a non-profit organization’s web address.

Otherwise, it is a web address for another entity

(a) Create a class named Invoice containing fields for an item number, name, quantity, price, and total cost. Create a constructor to pass the value of the item name, quantity, and price. Also include displayLine() method that calculates the total cost for the item (As price times quantity) then displays the item number, name, quantity price, and total cost. Save the class as Invoice.java.

(b) Create a class named TestInvoice whose main() method declares three invoice items. Provide values for each, and display them. Save the application as TestInvoice.java. 

Required Object Class and Driver Class ,Write a Java program to do the following

a) Read two-dimensional array (3 x3)

b) Find the diagonal elements of the array

Write a Java driven application with the following requirements:

1. Must enter names of students.

2. Enter test 1, 2 and 3 scores for each of my students.

3.  Program must calculate the average of each student.

4. Average of each student must appear below their names. ARRAY and MENU implementation should be necessary.

Create a method called emptySpace () this remove space between the name and the surname (Use a regular expression "replaceAll"). The emptySpace() method also Count the number of characters within the newly created string (nameSurname) and return the total number of Characters .

The total number of characters (Name and Surname) should be the size of your arrayAlphabetizer (type integer). Populate your arrayAlphabetizer with a series of random numbers between 10 and 50.

Display all arrayAlphabetizer elements and they are corresponding indexes before executing the sort() method and after executing the sort().

Allow the user to enter a value from the arrayAlphabetizer element to search for.

* * Loop through the array until you find the value (Use a Search function to locate the value with in the array) and replace that value with the character @.

 * *Print out arrayAlphabetizer with the replaced element..

Do you like reading books? If you do, then you must have encountered texts that have quite a wide space with dots in between them, just like pausing or thinking before proceeding the narration. Let's try doing that here in Python, shall we?

Input

Two lines containing a string on each.

some string

another string

Output

The first line contains the first inputted string.

The next three lines contains a dot symbol on each.

The last line contains the second inputted string.

some string

Quite tiring to write those things separated by commas and a single space, isn't it?

Then let's try coding it instead

Five lines containing a string on each.

A single line containing all the strings separated by a comma and a space.
