This is the question -
Three-letter acronyms are common in the business world. For example, in Java you use the IDE (Integrated Development Environment) in the JDK (Java Development Kit) to write programs used by the JVM (Java Virtual Machine) that you might send over a LAN (local area network). Programmers even use the acronym TLA to stand for three-letter acronym. Write a program that allows a user to enter three words, and display the appropriate three-letter acronym in all uppercase letters. If the user enters more than three words, ignore the extra words.
This is my code. It is acting like I have to enter the words seperarly which is what I don't think I have to do.
import java.util.*;
public class ThreeLetterAcronym {
public static void main(String[] args) {
// Write your code here
Scanner myObj = new Scanner(System.in); // Create a Scanner object
System.out.println("Enter three words:");
String[] str = new String[3];
String m="";…
Hello,
Please write a Calculator program in Java using the JavaFX libraries as we discussed in class. At a minimum, your calculator should handle addition, subtraction, multiplication and division of integer numbers. So basically you should be able to input a number, click an operation (+ - * /) button, then enter another number and hit = and you should see the result show up in the calculator display.
For part 2 add the functionality to the buttons. So that as a minimum your calculator programs should be able to handle the user inputting a multi digit integer, press + or - or * or /, then input another multi digit integer and then press the = button and the answer gets printed in the text label in your Calculator GUI.
java Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure.
(Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.)
Here are sample runs of the program:
Sample 1:
Enter a point with two coordinates: 2 2
Point (2.0, 2.0) is in the rectangle
Sample 2:
Enter a point with two coordinates: 6 4
Point (6.0, 4.0) is not in the rectangle
Analysis:
(Describe the problem including input and output in your own words.)
Design:
(Describe the major steps for solving the problem.)
Coding: (Go over your code step by step)
Testing: (Describe how you test this program). In other words run your code with sample outputs.

- Use Java ⮚ Roman numerals are represented by seven different symbols: I, V, X, L, C, D and M. ⮚ Symbol Value I 1 V 5 X 10 L 50 C 100 D 500 M 1000.⮚ For example, 2 is written as II in Roman numeral, just two ones added together. 12 is written as XII, which is simply X + II. The number 27 is written as XXVII, which is XX + V + II. ⮚ Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used: I can be placed before V (5) and X (10) to make 4 and 9. X can be placed before L (50) and C (100) to make 40 and 90. C can be placed before D (500) and M (1000) to make 400 and 900. ⮚ Given a roman numeral, convert it to an integerarrow_forwardIn Java ,write a program that will act like an Bank Management app. In order to access the app, the customer must enter their user name and their passcode. After 3 incorrect attempts at entering the user name and password, the program will end. The list of legitimate users along with their user ID, passcode and account balance will be provided to you. There are only 5 functions that can be carried out by the app: 1 - Deposit (adding money to the account) 2 - Withdrawal (removing money from the account) 3 - Balance Inquiry (check current balance) 4 - Transfer Balance (transfer balance from one account to another) 5 - Log Out (exits/ends the program) Note: No need for GUIarrow_forwardWrite a program in Java Object Oriented language that performs Addition, Subtraction, Multiplication and Division of two fractions.Make a program in Java Object Oriented language that performs Addition, Subtraction, Multiplication of two complex numbers (a+bi)Write a program in Object Oriented Java language that adds and subtracts two polynomials of the form ax2+bx+c In this case the menu will ask if you want to use fractions, complexes or polynomials and when you select the option, it will show all the requested operations.

Your discount chart should have three columns. The first column lists the items’ original price tag in CAD, and the second & third column provide the discounted prices after tax respectively in CAD and USD. All original price tags of the store are ended in .49 or .99. Your program should receive the maximum and minimum price tags, discount percentage (should be applied to original price tag), and CAD to USD exchange rate via keyboard entry. Develop you program based on the below sample results. Note that your program should check if the entries are valid values. In case of an invalid entry the program should ask the user to enter a value again as shown in the sample result. for rounding to 0.5 the round method of Math class in java.lang package might be helpful.

- Using Java,You are given an integer variable dollarAmount that will have an integer value of ten or larger. It is a value that we want to display on a check. In order to write out the amount in words, the first step is to determine the digit from the ones position and from tens position. We are going to take those first steps! Declare an integer variable named onesand initialize it to the value in the ones position from dollarAmount. Declare an integer variable named tensand initialize it to the value in the tens position from dollarAmount. Declare an integer variable namedhundreds and initialize it to the value in the hundreds position from dollarAmount. e.g. If dollarAmount = 1729,we would expect ones = 9, and tens = 2, and hundreds = 7. Output has been taken care of for you. Sample input/output: Input Output 1729 Ones: 9 Tens: 2 Hundreds: 7 19452 Ones: 2 Tens: 5 Hundreds: 4arrow_forwardIN JAVA. Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical.

You can refer to Powerpoint Slide #46 to use integers 0, 1, and 2 to represent rock, paper and scissors. At the beginning your program displays a welcome message "Welcome to Rock, Paper and Scissors game with my Computer", it then asks the user to enter his/her choice (only one of the choices: rock, paper and scissors is allowed). You can use a do... while loop to check the validity of the user input. Then your program use a random number generator to pick rock, or paper or scissors for the computer and displays computer’s pick. After that your program displays the result (either you win, or lose or a draw). After one game, your program asks user if he/she wants to continue. If the user decides to stop playing, your program displays how many games you played and how many time you win, lose and tie, and displays a "Thank you for…arrow_forward

Write a program that reads the user's first name and last name, and then use them to create a UPM email for the user. If the total number of characters in the user's full name, (first name + last name), is less than 10 letters, you should use the full name to create the user’s email. The general format of the user’s email should look like this: firstName.lastName@upm.edu.sa For example: First name = Ali Last name = Omar Total number of letters in both first and last names = 7 letters (<10 letters) Output = omar.ali@upm.edu.sa If the number of characters in the user's full name, (first name + last name), is greater than or equal to 10 letters, you should only use the first character in the user’s first name, and the whole last name to create an email.
