- Suppose that the average age of a Python programmer at Google is 30 and the average age of a Java programmer at Oracle is 39, and then consider an app where a programmer can check his or her own age against the average. This program would require the user input their age (as an integer stored in a variable named age) and their company (as a string stored in a variable named co) and then the program would tell them whether they are younger (and hipper) or older (and wiser) than the average age of the employees at THE SAME company. Which of the following would be True if a programmer was younger than the other programmers at THE SAME company? (age < 39 or co 'Oracle') and (co 'Google or age < 30) == == (co == 'Oracle' and age < 39) and (age < 30 and co == "Google') O (co 'Oracle' or co == "Google') and (age < 30 or age < 39) == (co 'Oracle' and age < 39) or (age < 30 and co == "Google') == None of these options O O O Oarrow_forward1. Write Java code to repeatedly print each single digit between 1 and 9 the number of times based upon its numeric value. Thus, you would get a triangle of the shape below where 1 prints once, 2 twice . and 9 prints 9 times. 1 22 333 4444 55555 666666 7777777 88888888 999999999arrow_forwardin java pls A local pizza shop is selling a large pizza for $9.99. Given the number of pizzas to order as input, output the subtotal for the pizzas, and then output the total after applying a sales tax of 6%. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("Subtotal: %.2f\n", yourValue); Ex: If the input is: 3 the output is: Subtotal: $29.97 Total due: $31.77arrow_forward
- In Java 8, I want the program to capture the current year and compare it to an input value. Specifically, the user is asked to enter the last two digits of a year that will be output. If those two digits are greater than the last two digits of the current year, the program will print to console a “19” before the two digits the user inputted. If the two digits that the use input are less than or equal to the last two digits of the current year, the program will print to the console a “20” before the two digits the user inputted. For instance, if the current year is 2023, and the user input the integer number “74”, the program would output to the console “1974”. If the current year is 2023, and the user input the integer number “19”, the program would output to the console “2019”. The user is not asked to enter the current year; the program captures that automatically. The user only enter the last two numbers of a year. Hopefully, that's enough to go by and clear enough. I need the code,…arrow_forwardWrite a FULL Java procedural program for a simple word guessing game. Below is an example of the required program behaviour. The bold text is user keyboard input. The player is allowed to guess one letter or the whole word incorrectly up to 5 times; each incorrect guess is called a “strike”. The program starts by displaying one full stop (’.’) for each character of the secret word. You may assume the word is hardcoded into the game, is in lower case, and is of length greater than one. In each round of the game, the game first checks if the player has reached the maxinum number of strikes; if so, the player loses and the game ends. If not, the game prints an input prompt. The player then guesses either one letter (by entering a single character) or the whole word (by entering multiple characters). If a single letter is guessed correctly, meaning the character occurs in the word, the game reveals the positions of those occurrences in the word and proceeds to the next round. If the whole…arrow_forwardn this lab, you complete a prewritten Python 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 make 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.arrow_forward
