Question
Writing a Modular Program in Java
Summary
In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31.
Instructions
- Notice that variables have been declared for you.
- Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user.
- Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints.
- Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date.
- Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this program.
- Execute the program entering the following date:month = 9, day = 21, year = 2002Observe the output of this program.

Bonuses are calculated based on an employee’s productivity score as shown below. A productivity score is calculated by first dividing an employee’s transactions dollar value by the number of transactions and then dividing the result by the number of shifts worked.

- in Java Tasks Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 3. The computer's choice is displayed. Tasks 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.) C. If one player chooses paper and the other player chooses rock, then paper wins.

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ドル.00. The first five letters or numbers are included in the minimum charge; there is a 4ドル charge for each additional character. If the sign is made of oak, add 20ドル.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional 15ドル 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...arrow_forward
