Java Calculating the User's Sum Write a complete program that reads in numbers and calculates the sum of the numbers in that range. Code Specifications In the main method, read input from the user. Read in two integers from the user: a lower end of the range and an upper end of the range. Check if the numbers are valid: the lower number cannot be greater than the upper number. If the numbers are invalid, use a loop to ask for new numbers. Continue looping until you get two valid values. Write a method called calculateTheSum. The method takes in a lower and upper end of the range. The method calculates the sum of all values from lower (inclusive) to upper (inclusive). Invoke the method from main the output the result. Test Cases I recommend testing your code using the test cases below. I've listed the user inputs along with a sample of the result. User Inputs Result lower = 10, upper = 1 the program should ask for new input lower = 5, upper = -5 the program should ask…

Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…
Help code in Java 21. Compound InterestWhen a bank account pays compound interest, it pays interest not only on the principal amount thatwas deposited into the account, but also on the interest that has accumulated over time. Suppose youwant to deposit some money into a savings account, and let the account earn compound interest for acertain number of years. The formula for calculating the balance of the account after a specifiednumber of years is:A = P ( 1 + r n ) n tThe terms in the formula are:A is the amount of money in the account after the specified number of years.P is the principal amount that was originally deposited into the account.r is the annual interest rate.n is the number of times per year that the interest is compounded.t is the specified number of years.Write a program that makes the calculation for you. The program should ask the user to input thefollowing:The amount of principal originally deposited into the accountThe annual interest rate paid by the accountThe…
5. Palindrome Detector A palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes: Able was I, ere I saw Elba A man, a plan, a canal, Panama Desserts, I stressed Kayak Write a boolean method that uses recursion to determine whether a string argument is a palindrome. The method should return true if the argument reads the same forward and backward. Demonstrate the method in a program.
Java Programming: Write a command line game that plays a simple version of blackjack. The program should generate random numbers between 1 and 10 each time the player gets a card. It should keep a running total of the players cards, and ask the player whether or not it should deal another card. Sample output for the game is written below. Your program should produce the same output. The players get two cards to start with. Then they are asked if they want more cards. Players can continue to take as many cards as they like. The goal is to get close to 21 without going over. If the total is greater than 21 we say the player "busted".
JAVA Write a program that plays a number-guessing game to guess a secret number randomly generated within the range 1 and 10. The user will get as many numbers of tries as he/she needs to guess the number. Tell the users if their guess is right or wrong and if their guess is wrong let them try to guess the number again. You have solved a similar problem in a previous lab using a while loop. You must generate the secret number using the Java Random class. When the user guesses a number he/she will have to take an input of his guessed number from the keyboard. The user will have to take as many inputs as needed to guess the correct secret-number. That means the code will keep looping as long as the guess is different from the secret number. You also need to count the number of tries and report the count at the end. Use a do-while loop to prompt the user to guess again if the guess is wrong. Make sure that it doesn't mess up the output if you guess the secret number on the first try.…
Python Programming ONLY PLEASE NO JAVA Use recursion to determine the number of digits in an integer n. Hint: If n is < 10, it has one digit. Otherwise, it has one more digit than n / 10. Write the method and then write a test program to test the method Your test program must: Ask the user for a number Print the number of digits in that number. (describe the numbers printed to the console) Use program headers and method header comments in your code.
basic java please Write a void method named emptyBox()that accepts two parameters: the first parameter should be the height of a box to be drawn, and the second parameter will be the width. The method should then draw an empty box of the correct size. For example, the call emptyBox(8, 5) should produce the following output: ***** * * * * * * * * * * * * ***** The width of the box is 5. The middle lines have 3 spaces in the middle. The height of the box is 8. The middle columns have 6 spaces
