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…

- 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_forwardQuestion 3: Write a Java program that takes two numbers from user as input and display the sum (addition), multiply, subtract, divide and remainder of two numbers.

- The body mass index, BMI, is a measure used to determine if a person is overweight or not. We can calculate BMI from the weight of the person (in pounds) and the height (in inches) of the person.The formula for calculating BMI is:BMI = (weightInPounds * 703) divided by (heightInInches squared)In this problem, you will develop a Java program as a BMI calculator, that reads the user’s weight in pounds and height in inches, then calculates and displays the user’s body mass index BMI. Also, display the following information {from the US Department of Health} so the user can evaluate his/her BMI:BMI values:Underweight: less than 18.5Normal: between 18.5 and 24.9Overweight: between 25 and 29.9Obese: 30 or greaterarrow_forwardwrite java program using Conditional statements and looping statements for the following statements: National University of Science & Technology NUST has conducted a programming test forlevel1 ITMB students and pass mark for the exam is 60.
